Authentification and Database problems

My Pydio 7 was working find but since i have upgrade to Pydio 8, authentification doen’t work.

I have an error : Network error h is null

can you switch your Pydio to debug mode so that we have more infos about the error ?
See conf/bootstrap_context.php
Change this line to true: define(“AJXP_SERVER_DEBUG” , true);
and then send us the stack,

Verify mysqli extension and enable it if it was disabled.

I’m getting this in Pydio core 8.2.5, was it ever resolved? Users are reporting frequent disconnects.
