This problem in Linux client and OSX client

[eric-it6]

General informations

Docker host's operating system : Ubuntu 20.04

Docker informations

OCS Image version: 2.9
MySQL Image version: 5.7

We have the same problem. With version 2.8.1 everything works fine.

In the DB-Container following message appears:
2021-06-15T14:17:19.293544Z 27923 [Note] Aborted connection 27923 to db: 'ocsweb' user: 'ocs' host: '10.0.5.18' (Got an error reading communication packets)

After some research, I came across on this: https://dba.stackexchange.com/questions/19135/mysql-error-reading-communication-packets
Maybe the problem is not the OCS enviroment. In our surrounding this error would make sense, because the connection drops only after some time.

Perhaps it will help you.

Hey,

Are you using the provided compose or do you connect to an external database ?

Regards,
Gilles.

[eric-it6]

Hey,

yes we use the compose file, but the containers run behind traefik.

Many greetings
Eric

see my issue #59

try to not mount the /usr/share part in compose file

or try to remove var.php

i had 500 error and found that a table was missing. and this was because the update process of the database wasnt executed.
