Here's the error message in the application log

Hello,

I suspect that the certificate warning that you receive is related to this help article
https://help.remotedesktopmanager.com/kb_security_certificatevalidation.html

Best regards,

Hi Jeff,
I've checked the certificate and it is valid, however, this is a PKI generated certificate which is trusted by my domain-joined computer and all web browsers. RDM had no issues with it whatsoever until recently. The problem for me now is that I cannot get the Remember and Continue dialogue to come up, it seems to come up but in the background making the application unusable until I force-close it.

I can't see the "remember a certificate" dialogue because it seems to appear behind the main window and I tried with the main application window "maximised" and "restored"

REMEMBER A CERTIFICATE
It is possible for Remote Desktop Manager to remember a certificate when prompted to verify it.

Hello,

Are you able to bring the window up front if you pressing ALT + TAB?

Best regards,

I have tried Alt+Tab and Win+Tab to no avail. I see the main window but nothing else. I've worked around this by enabling the "Ignore application certificate errors" but that is a security risk.

Hello Crater,

Would you mind going under File -> Options -> User Interface and check the "Always on top" option?
I suspect that this option might help.

Best regards,
