Error code 100000421
I have trouble connecting to the meeting on my iMac desktop and get error code 100000421, while my macbook laptop and Android phone work fine. Have searched on the internet and nothing found.
Solved. Uninstall zoom with the built-in uninstaller rather than the system one, then reinstall it, and the problem is gone.
