Error communication with server

Hello,

We have an error message since the migration when we start Moodle : "en error occurred communicating with the server"

If we close the popup, the connexion is ok. But the popup appear often. It's very unpleasant.

Before migration we have not this problem.

We have migrated moodle from 3.5.1 to 3.7

We have migrated php 7.0 to 7.2

Have you an idea ?
