TrueNAS upgrade causing certificate issues

I recently upgraded from FreeNAS 11.5 to TrueNAS 12 -U1, but now I can’t access the web GUI, as I get the error message “ERR_SSL_KEY_USAGE_INCOMPATIBLE”.
I"m able to see and browse my SMB shares in Windows no problem, I just can’t access the webGUI to manage the system. Is there an easy fix for this issue?

Thanks

Have you tried another browser?

I tried Firefox and it let me connect and log in. I guess Chrome was freaking out
when it saw a self-signed cert?

The new version of Chrome seems to do that sometimes.
