If you are reading this post as someone who just made their account and cannot log in, I am making this post for you.
I had created my account, but I could not log in. Progress would continue without error message or timeout, which appears to be the case for anyone who has created an account but not verified their email yet.
However, I had not received the email to verify my signup mailbox. It appears that this can take a long time to be received, over 2 hours in my case.
So if you are attempting to sign up and log in, you may need to wait a while for an email to come in from admin@ttrpg.network
I hope this helps, cheers!
