I’m new to this forum so I hope it’s okay to just ask away 
I updated from Fedora 43 to 44 last week, which went mostly uneventful. Except for Webex, the main app we use for communication at my Workplace.
I checked the logs and saw that it was throwing SSL verification errors and therefore refusing to connect to its own servers (wbx2.com).
Trying to use webex in the browser still works perfectly fine, so I assume the error comes either from webex itself or how the OS does SSL verification.
I saw the change of dropping cert.pem with F44, so I assumed this could be the culprit, but running ln -s /etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem /etc/pki/tls/cert.pem did not resolve the issue either.
Finally I’ve asked around in my team, and my colleagues who are still on Fedora 43 do not have the same issues, which leads me to believe the problem lies somewhere within the last update and not necessarily within webex.
My obvious next step would be to ask someone else to update to F44, to see if they have the same problems, but I don’t think my colleagues want to be forced to use webex’ horrible web version as well, so they’re holding out on the update for now.
Edit:
The error itself looks something like this:
<Warn> [106565:0x1a109][]HttpRequestManager.cpp:2354 operator():CF #0 (default):{"id":"HTTP request failed","uri":"https://u2c.wbx2.com","method":"GET","action":"<redacted>","defaultUrl":"<redacted>","currentUrl":"<redacted>","retryable":false,"trackingId":"<redacted>","cancellationId":"<redacted>","httpStatus":0,"errorCode":337047686,"sslError":true,"networkTimings":[2,14,0,0,0,0]}
