Proxy authentication required (gitlab sso token issue

[mrmm2021]

Hi!

I need some help please.

I'm trying to authenticate with gitlab sso from mattermost team edition installed with docker.

The error i can see in docker log is:

{"level":"error","ts":1622831461.755552,"caller":"web/oauth.go:282","msg":"AuthorizeOAuthUser: Falló la solicitud del Token., Post \"https://domain/oauth/token\": Proxy authentication required"}

The pem from our gitlab server is located in:

• ./volumes/web/cert/pki_chain.pem:/etc/ssl/certs/pki_chain.pem:ro

Any idea please?

Thanks in advance!
