Zoom Workplace stuck at connecting

When trying to join a meeting the window stays on “connecting” and never joins the meeting. The user having the issue has been able to connect to meetings up until today. He works from home and has not changed ISPs (Star Link). I cleared the Zoom cache, uninstalled/reinstalled the latest version of Zoom Workplace, and updated the ZScaler app and policy. We have not had any other users report the error. The error code is 104103. He is able to use the web version of Zoom. We also tried creating several other meetings to test with, but we received the same result. The user is also able to access all network resources as well as the internet. Any help with this issue is greatly appreciated.
