The SSL connection could not be established, see inner exception

Hello,

Thank you for reaching out to us regarding this,

Could you please specify the version of RDM you are currently using?

I'm also wondering if you could provide us with a screenshot of this error message?

Let me know,

Best regards,

on versions 2024.1.15 and 2024.1.19 when trying to connect to devolutions hub personal data source




The odd thing is the custom proxy settings were pulled from the system default config.

I could happily accept using custom settings and ignoring system default if it stayed on custom settings, but it doesn't.

Hello,

Sorry for the late reply.

Do you have the entire error message details under Help -> Application Logs? Could you paste us the entire call stack of the error message here please.

Best regards,

Doesn't show in the application logs, but simple enough to reproduce.

As there isn't any more visibility than this I have to assume that RDM is ignoring my proxy settings and trying to get out direct, which is blocked. if I knew which URL is targeted when this exception happens I could grab proxy and firewall logs to correlate and confirm.

My assumption was correct. Remote Desktop Manager is trying to connect to hub.devolutions.com directly through the firewall rather than use either the default proxy settings on the system or the custom proxy settings I have defined.

Hello thomasfeely,

Thank you for this feedback.

An internal ticket has been opened to investigate this issue.

I will post here when I will have news on this case.

In the meantime, the workaround will be to continue to use 2024.1.15.0.
This version can be downloaded here:
https://devolutions.net/remote-desktop-manager/home/previousversions/

Best regards,

I'm currently working around this by logging into devolutions hub personal and using an export as a local data source so I can stay on the latest code.

Happy to grab any logs or info if you'd like me to test. Great that you're looking into this.
