No new user can register on the website. We are using Netlify Identity. After a new user gets the “email address verification email” and click “Confirm your email address” link in it, the webpage comes up but in a short time there he gives an 504 error and the following message:
“There was an error verifying your account. Please try again or contact an administrator.”
Please help, what could be the problem? Some days ago it worked well, so the problem is quite new.
