What version are you running?
RB 7.0.3, RBT 5.2
What steps will reproduce the problem?
We use a SSL Certificate issued by our company, with a root certificate installed on the client machine.  

Using rbt post fails with




ERROR: Could not reach the Review Board server at https://xxxx.com/: The SSL certificate used for "xxxx.com" has an untrusted or self-signed certificate in the chain that cannot currently be verified by RBTools.


Using rbt post --disable-ssl-verification will allow use to posty a review
Putting DISABLE_SSL_VERIFICATION = True in the repository (project root) .reviewboardrc file does not allow us to post the review - Same error message
Putting DISABLE_SSL_VERIFICATION = True in the user local .reviewboardrc file does not allow us to post the review - Same error message

What operating system are you using?
kubuntu 22.04
Attach the debug out from the command.

$ rbt post --parent=RM6960 --debug
