| The Finder can’t find the ThinPrint Hub anymore after moving it to another network. | • Using the web console, enter a valid gateway in IPv4 Settings. • In the Hub Finder, specify the subnet to be searched. |
| The Hub Finder finds the ThinPrint Hub, but its IP address belongs to another subnet. | The Hub may have been previously configured in another subnet, and its IPv4 network settings is set to Manual configuration. → Use the Finder to change the IP address of the Hub in question. |
| The Hub's IP address belongs to another subnet, and the Hub Finder does not display it. | The Hub may have been previously configured in another subnet, and its IPv4 network settings is set to Manual configuration. → Alternative 1: • Proceed as described in the section Resetting the Hub settings to default values (factory reset). → Alternative 2: • Start a virtual machine on the physical network where the Hub is located, and then set a manual IPv4 address from the Hub’s network in that virtual machine. • Open a browser in the virtual machine, connect to the Hub, and change its IPv4 network setting to DHCP. • Use the Hub Finder to find out the Hub’s new, DHCP-assigned IP address. |
| ThinPrint Hub disappears from the Hub Finder five minutes after its system start. | • With enabling Make ThinPrint Hub invisible for the ThinPrint Hub Finder the ThinPrint Hub won’t be shown in the Finder anymore. |
| Hub Finder shows ThinPrint Hub as Read Only five minutes after its system start. | • Read Only becomes active with changing either the password the first time or the option Make ThinPrint Hub invisible for the ThinPrint Hub Finder. |
| The ThinPrint Hub gets its old IP address (per DHCP) after a reboot even though it has been changed using the Finder beforehand. | • Changing the Hub’s IPv4 address using the Finder doesn’t affect the DHCP setting. This must be changed using the web console to Manual configuration afterwards, if necessary. |
| While remotely managing a Hub from ezeep Blue's admin console, the hub is unexpectedly logged out, which means the Hub's login window appears (can occur with firmware version 1.13 to 1.16). | • Ensure that all Hubs to be configured remotely (using the same browser) at the same time are logged in. • Or configure each Hub individually. |
| An uploaded certificate doesn’t work with the ThinPrint Client. | • Check whether the certificate was issued for server authentication even if is to be used for the ThinPrint Client (Certificates). • Check the Hub’s System Time. |
| An uploaded certificate doesn’t work with the web console. | • Check whether the certificate name matches the address of the ThinPrint Hub (Certificates). • Check whether the certificate was issued for server authentication (Certificates). • Check the Hub’s System Time. |
| In the list of uploaded certificates, one is marked expired. | Compare the entry in the Valid column with the system time of the Hub. |
| With importing the PowerShell module the following message appears: “Import-Module: Could not load file or assembly 'file:///F:\hub-powershell\TPHubPS.dll' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515)” | • The file TPHubPS.dll is blocked by Windows. See Installing the PowerShell module. |
| With PowerShell authentication on the Hub the following message appears: “Get-TPHubAuthentication: An error occurred while sending the request.” | • wrong target address; see Set-TPHubUri • The Hub doesn’t accept the server certificate; perform Set-TPHubServerCertificateValidation before. |
| With PowerShell authentication on the Hub the following message appears: “Get-TPHubAuthentication: Method Not Allowed” | • Check if you accidentally specified the URL with http instead of https. • example: Set-TPHubUri -Uri "https://192.168.149.12" |
| With PowerShell authentication on the Hub the following message appears: “Get-TPHubAuthentication: Request to https://192.168.209.67/api/v1/Security/Token failed. An error occurred while sending the request.” | • Make sure that the version of the PowerShell module you are using belongs to that of the Hub. |
| With PowerShell authentication on the Hub using Get-TPHubPPServerCheck the following message appears: “Authorization has been denied for this request.” | • First, use the Get-TPHubAuthentication cmdlet to log on to the Hub. |
| With changing the IP address using PowerShell the message “Set-TPHubNetworkIPV4: A task was canceled.” appears. | • After setting the new IPv4 address the Hub PowerShell module waits for the answer from the old IP address. After a timeout the PowerShell module shows the message even though everything was configured as requested. • You can suppress this message. |
| When testing the Personal Printing server via PowerShell using Get-TPHubPPServerCheck, the following message appears: “The request timed out” | • Just repeat the same process. |
| When testing the Personal Printing server via PowerShell using Get-TPHubPPServerCheck, the following message appears: “The remote server returned an error: (500) Internal Server Error.” | • Check the validity of the installed license keys on the relevant Personal Printing server. |
| With printing the following message appears on the ThinPrint server: “Connection reset by peer”. | • The ThinPrint Engine can’t establish a connection to the Hub’s ThinPrint Client. • Perform a ping from the ThinPrint server to the box; on this, use the hostname, if the printer object on the ThinPrint server also uses this. • Perform a telnet from the ThinPrint server to the box: telnet <address of the box> 4000 • Disable IPv6 on the ThinPrint server. • Disable the ThinPrint server’s firewall temporarily. • Recreate the relevant printer object on the ThinPrint server – best using AutoConnect, or using the Management Services to avoid type errors. |
| The ThinPrint Hub doesn’t connect to the Connection Service. | • Enable the Connection Service option in the ThinPrint menu. Here, check all settings. Client ID and Authentication Key and the settings in the Connection Service console must match. • If – at the same time (UTC time) – the log file in the System menu shows connector "con" booted, the Hub started its Connection Service module and tries to connect to the Connection Service. • On a workstation in the Hub’s subnet test the connection to the Connection Service using telnet on the Command Prompt: telnet <IP_connection_service> 4001 |
| Firmware version 1.0.51: The ThinPrint Hub doesn’t reconnect to the Connection Service automatically after restarting the server the Connection Service is installed on. | • Perform a firmware update to version 1.0.54 or later. To do so, see Downloading and installing a firmware update. |
| Firmware version 1.0.51/1.0.54: Single pages are missing or entire print jobs vanish when printing to a specific printer model without any error message on the Hub. | • Perform a firmware update to version 1.0.60 or later. To do so, see Downloading and installing a firmware update. Otherwise: • Check whether there is an alternative printer driver (PCL5 / PCL6, PostScript) for this printer model which works. • Host-based print drivers are not supported since they use the computer’s (host’s) resources to process the print job. These so-called GDI printers need to be directly connected to a printer driver host. |
| Firmware version 1.0.51/1.0.54: With printing via LPR/LPD the following message appears on the ThinPrint server (maybe sporadically): “The client has rejected the print job. ... Error in function No. 0, Error code 80efea6e” | • Perform a firmware update to version 1.0.60 or later. To do so, see Downloading and installing a firmware update. Otherwise: • With this printer, select the option Start printing after the last page is spooled on the ThinPrint server and disable the Advanced printing features (first Illustration below) • Choose the print mode Standard TCP/IP. |
| Firmware version 1.2.23: When setting up IEEE 802.1X authentication with PEAP for the first time, the configuration can not be saved. The Save button remains visible. | • Perform a firmware update to version 1.2.25 and then to 1.3.9 or later. To do so, see Downloading and installing a firmware update. Otherwise, you can use the following workaround: • Add any client certificate. • Select TLS instead of PEAP. Here, specify the client certificate and an associated root or intermediate certificate. • Save the TLS configuration by clicking the Save button. • Change the authentication from TLS to PEAP. • Re-enter the PEAP settings and save them. |
| When trying to update one of the firmware versions 1.2.23 to 1.3.11 via PowerShell, the following output appears, among others (see the screenshot below) : “Handle: 1320 SafeFileHandle: Microsoft.Win32.SafeHandles.SafeFileHandle CanTimeout: False” | • For updating, use the module TPHubPS.Update.dll instead of TPHubPS.dll. or • Perform the update via the web console. (TPHubPS.Update.dll has the following reduced set of cmdlets: Clear-TPHubAuthentication, Get-TPHubAuthentication, Get-TPHubNetworkIPV4, Get-TPHubProxy, Get-TPHubRequestTimeout, Get-TPHubServerCertificateValidation, Get-TPHubUri, Set-TPHubNetworkIPV4, Set-TPHubPassword, Set-TPHubProxy, Set-TPHubRequestTimeout, Set-TPHubServerCertificateValidation, Set-TPHubUri, Update-TPHubFirmware) |
| Firmware version 1.3.9/1.3.11: An update to version 1.8.29 or later isn't possible. | The firmware package 1.8.29 is somewhat bigger than other versions, and 1.3.x cannot handle files of that size. From 1.3.x, you must first update to 1.4.21, 1.5.19, 1.6.4 or 1.7.14. In a second step, you can update to 1.8.29 and higher. |
| If USB printers are connected, it may happen that print jobs are no longer printed after an update to firmware version 1.7.14 or after a backup of a version older than 1.7.14 has been imported, or – if several USB printers are connected – on the wrong printer. | Causes: • Either the printer in question has been changed from one USB port to another. • Or the ThinPrint Client of the Hub reassigned the printer IDs to the USB ports. Workaround: • In Managing Printers, delete all printers connected to USB. • Save the configuration by clicking the Save button. • Add the printers again. • Save the configuration again by clicking the Save button. |
| When trying to query the IsActive property of Get-TPHubFindPrintersSettings, the following message appears: “The property 'IsActive' cannot be found on this object. Verify that the property exists and can be set.” | • The IsActive property is implemented incorrectly. Please use IsAvtive instead of IsActive. • This version 1.4.18 issue will be fixed with the next release. |
| When trying to access the Hub configuration site your modern browser throws the error ERR_SSL_VERSION_OR_CIPHER_MISMATCH. | • Your ThinPrint Hub runs an old firmware version. You can update it using the PowerShell script (you need to edit the ThinPrint Hub address, the password, and the path to the firmware file)
