504 Gateway Time-out since VPS OVH migration

Hello everyone

I migrate OVH VPS server which hosted several dockers with seafile pro server and others website and database docker server.
We migrate because the VPS was not enough powerfull to work well with all dockers.
Before the migration, seafile works. But since we relaunched it after that, we had 504 Gatework Time-Out.

Instead I searched solutions on the web but any of it works at the moment.

I answer to my question.
The problem comes from https. If it’s disabled, Seafile works as well.
I have others dockers with active service on https and there are any problem.
