Registration takes long for completing

Can someone help me in a direction to find out the issue with the registration app.
When a customer is registering it takes almost 1 minute to complete and login the customer.
Other actions in Nextcloud goes fast.

I am using NGINX 10.1 and nextcloud 12.03
Registration app is 0.3.1

Hello,
I’m facing the same issue. Any suggestion?

what server are you using? sometime this could be some caching issue. or your database performance.
