JobServer https error - ERR_HTTP2_INADEQUATE_TRANSPORT_SECURITY

Hi


I am facing error " ERR_HTTP2_INADEQUATE_TRANSPORT_SECURITY "when accessing JobServer http server. I can rach the server when it is not ssl enabled withut an issue. 

I set https with binding certificate for the service and eanbling ssl in the JobServer configuration.

Issue is present only on one JobServer and might be connected to the fact that specila restrictions are set on that JobServer.

Job server that runs on another network is working without issues as well on https.

Do you have any ideas what to check to enable JobServer https server?

Many thanks for ideas

Andrej
