TigerVNC X509 Encryption: The certificate for <host> couldn't be verified

Published 7 years ago

Hello,

when i try to connect to a TigerVNC server configured with X509 encryption i get the following warning every time i connect:

The certificate used on the TigerVNC server is not expired and released by Let's Encrypt.

I exported the certificate and tested it with powershell, as explained in the link below; it return "True" with no error.

Hi,

I've made some changes to the certificate validation code.

It should now correctly validate the certificate.

The fix will be available in the next release.

Hi,

This Mathieu Morrissette from the Devolutions Security Team.

I just wanted to let you know that we have made changes to the certificate validation mechanism in RDM 2021.2.9.0 and above that should solve issues some users were experiencing.

Let us know if you still have the certificate warning message.

Best regards,
