Hello @podonnell1 ,
welcome to the Forum!
Could you check your server disk space? Maybe it run full and the user DB file has got corrupted. It can be resolved by sharing a replacement, see How to reset the knimeadmin password from the CLI - #9 by marvin.kickuth
If it doesn’t work please reach out us via support@knime.com and send us the server logs and server version for further troubleshooting.
Best,
Dora
