Any good resources/Discord servers (to discuss with other devs) for troubleshooting user login/email verification issues?

I have a self-hosted instance and was able to make the admin user, but when trying to create a new test user, the user does not get the verification email.

I assume its related to this issue because I see the same issue but on login rather than sign up: https://github.com/LemmyNet/lemmy-ui/issues/1080

I am able to create the new user but get no email verification and then when I try to login the login button gets stuck with the spinner. No frontend console logs so I assume something is dying server-side and not bubbling the error.

Really just looking for some guidance/links to docs on how I can access logs to troubleshoot server-side errors (and my gut tells me maybe an email issue but I am a novice in this space so not sure).

Any help is appreciated.

Thank you.
