Teamcity "Updates" Page not working after upgrading to 2020.01


I have upgraded the Teamcity to 2020.01, post that "Updates" page under Administration is not working and getting below error:

Unable to check for updates via URL "": PKIX path building failed: unable to find valid certification path to requested target (see details in teamcity-server.log).

Also I'm a bit new to Teamcity. Can you guide and have checked the proxy setting which is fine.

I had this issue a while ago too. It was due to my corporate firewall (WatchGuard) intercepting web request and rewriting certificate authority for HTTPS transactions. We added the build machine in the list of exclusion and it fixed the issue. I guess it could happens with any local network with custom TLS validation layer.
