RDM can't connect Devolutions Server
Hello,
RDM returns error by connecting to 1 of 5 servers with Devolutions Server. Web access to this server is OK.
The error:
Devolutions.RemoteDesktopManager.Business.TryGoOfflineException: Could not obtain data source settings. The server might not be responding.
at Devolutions.RemoteDesktopManager.Business.DataSources.RDMSConnectionDataSource.GetDataSourceSettings(String repositoryID)
at Devolutions.RemoteDesktopManager.Business.DataSources.RDMSConnectionDataSource.GetDataSourceSettings()

at Devolutions.RemoteDesktopManager.Managers.ConnectionManager.LoadConnectionsFromDataSource(ConnectionEngine engine, Boolean hasChanged)
at Devolutions.RemoteDesktopManager.Managers.ConnectionManager.LoadConnections(BaseConnectionDataSource dataSource)The issue started after upgrade the devolutions server to the version 2024.1.6.0. We tried update that affected server to the latest 2024.1.8.0 but the issue still persists.
Unistall the devolutions server and install it back is the same issue.
RDM is in the last version 2024.1.20.0 64-bit
Thanks for your help.

Hello jmalina,
Normally this error message means that either the server is down (obviously not your case) or that the server is taking to much time to respond.
The Devolutions Server datasource configuration in RDM has an advanced parameter Connection Timeout that might help.
When you say that the error is happening on 1 of 5 servers do you mean that 1 of the 5 server was updated to 2024.1.6.0 or that all servers were updated but only one has the issue?
When you say that you uninstalled and and install it back, do you mean you rolled back the server to it's previous version?
Best regards,

Hello Benoit,
I'm a colleague of jmalina's and I will add information about our problem.
We have upgraded all of 5 our servers to version 2024.1.6.0 and one of these server is affected with this issue. We have made upgrade from version 2023.x.x.x (I don't exactly remeber previous version) to version 2024.1.6.0. The issue started after this upgrade on one our sever. Other servers are ok
We have also tried make upgrade newer version 2024.1.8.0 on this server, but issue still persist.
With the uninstall, my colleague meant that we tried uninstalling the Devolutions server instance and installing it back on affected server. We didn't try downgrade version on this server.
Best regards

Hello Jakub,
It will be easier to troubleshoot this issue in a support session.
I will open a case for you and send you a link to book an emergency session.

Hello Jakub,
Thank you for being so patient.
We have solved the HTTP Unauthorized issue in RDM by disabling the Basic Authentication of the DVLS web application in IIS Manager. With ASP.Net 8, the Basic Authentication must not be enabled or installed.
