SSL connection has been closed unexpectedly

Hi there,
I did $flask db stamp head try to update the Render database, but it got this error.
sqlalchemy.exc.OperationalError: (psycopg2.OperationalError) connection to server at "" (, port 5432 failed: SSL connection has been closed unexpectedly
I tried to set pool_pre_ping = True, but the error is still remained.
The version of psycopg2 is 2.8.1.
Hope you guys can help me to figure out this error, thanks lots!

Already solved, cause I change to another IP address without adding into access control list.

Glad you were able to resolve your issue.

Thanks for using Render
