Unable to login

I have started a Docker convertx instance using Docker Compose. Initially, the only change I made was swapping "3000:3000" to "3001:3000" since another container already uses the 3000 port in my setup. I have been able to access the setup page and login page, but when I enter my credentials into the login page, it simply returns me to the login page to reenter my credentials. I am unable to reach the main conversion page. Any help would be much appreciated!
