Unable to get into admin page on self hosted service

Hi all,
Just having an issue with the self hosted admin page. This is a brand new service, installed it for the first time yesterday. It’s up and running and i’ve migrated my passwords into it. The issue is when I try and go to the admin page. It asks for my email address which I enter. It then redirects me to a 404 page as it tries to go to https://bitwarden.domain.com/login (where I believe it should end with /#/login)

I also never get an e-mail. I checked my mail server logs and found this:
Mar 11 18:37:32 zimbra postfix/postscreen[28085]: CONNECT from [192.168.1.124]:40706 to [192.168.1.200]:25
Mar 11 18:37:32 zimbra postfix/postscreen[28085]: ALLOWLISTED [192.168.1.124]:40706
Mar 11 18:37:32 zimbra postfix/smtpd[28086]: connect from bitwarden.domain.com[192.168.1.124]
Mar 11 18:37:32 zimbra postfix/smtpd[28086]: lost connection after EHLO from bitwarden.domain.com[192.168.1.124]
Mar 11 18:37:32 zimbra postfix/smtpd[28086]: disconnect from bitwarden.domain.com[192.168.1.124] ehlo=1 commands=1

Any ideas?

When I was troubleshooting the issue I found it was the smtp auth that was causing it. I removed the username and password (mail server is on same network), it seemed to work. I think I need to escape the password or encapsulate it within " " possibly.

That also fixed the redirect issue too… how odd.
