Stupid question first… Are you 100% that the primary email at https://community.drownedinsound.com/u/JoJoMarty/preferences/account is correct?
Have you tried changing that email, then trying the forgot password method? Not sure if it asks you to put your password in again to change email though…
Can you add an “Alternate Email”?
Have you tried “Skip the password; email me a login link” in the login popup?
It’s very strange that you’re not getting the emails though. I just tried the forgot password method with your username, in case there’s some sort of IP blocking going on, so perhaps now you’ll receive one? I just tried a “Forgot Password” on my account and received the email instantly.
I can’t see any issues on the Discourse boards themselves, so nothing to suggest that this is a site-wide problem.
