Load scripts backend strange problem

Permalink
Hello. I have a strange problem loading resources after logging into the backend. Therefore, e.g. site map or other backend functions do not work.

It's exactly about 2 resources.

Errors:

GET domainname/ccm/assets/localization/jquery/ui/js net::ERR_HTTP2_PROTOCOL_ERROR
info:826 GET domainname/ccm/assets/localization/core/js net::ERR_HTTP2_PROTOCOL_ERROR

Uncaught ReferenceError: ccmi18n_tourist is not defined
Uncaught TypeError: b(...).concreteHelpLauncher is not a function

After trying to find a solution to the problem, I came across an article in which someone turned off gzip for certain resources.

I tried this solution and turned off gzip compression in htacess and the problem disappeared.

Therefore, I would like to ask if anyone has encountered this problem on OVH servers or is it a problem closely related to any configuration that OVH has and HTTP 2.0?

OVH server, Conrete5 version: 8.5.2, PHP 7.2.x or 7.3.x
