OpenID Connect provider discovery failed

[Fadeev Dimitri]

Hi,

We have a Jira Enterprise SSO with Keycloak in production and in Test.

Kyecloak, production-JIRA and test-JIRA are on the same network. In production, everything works without errors, and in the test, when we try to Discover Provider, we get the following error in logs.

It was a Proxy Problem

It seems you are using codecentric's app for OIDC. Maybe you should try to contact them? 

I contacted them once and they were very kind and helpful.
