Help trying to setup after crash.

Hello, I recently lost my cache drive wit hall my docker configurations in Unraid. I did not have a backup of them, so I am setting them up from scratch. I am trying to setup Sonarr and I cannot get it to load. When I load the Sonarr web address it prompts me for the username and password, I enter them and it does nothing, it just keeps asking for the username and password. I am uncertain how to get past this so I can setup sonarr again.
