#### Summary

We have hosted mattermost server and gitlab server on same VM, we are using gitlab sso which is integrated with our ldap.  
Later we have decided go mattermost on internet and assigned the VM public IP (corporate proxy server). it has been accessed with [http://IP:8065](http://IP:8065)  
and gitlab is also accessible over internet [http://IP](http://IP).  
We can able to redirect from mattermost to gitlab , authentication is also happening with ldap, but when its been authenticated it says

The redirect URI included is not valid while

#### Steps to reproduce

Both Gitlab and mattermost are hosted over public ip.

Below are the config.json

[http://internetIP](http://internetIP)  
[http://internetIP/api/4/user](http://internetIP/api/4/user)  
[http://internetIP/oauth/authorize](http://internetIP/oauth/authorize)  
[http://internetIP/outh/token](http://internetIP/outh/token)

Gitlab config is  
[http://internetIP:8065/login/gitlab/complete/](http://internetIP:8065/login/gitlab/complete/)  
[http://InternetIP:8065/signup/gitlab/complete/](http://InternetIP:8065/signup/gitlab/complete/)

#### Expected behavior

Mattermost should go to gitlab authenticate and redirect to mattermost again

#### Observed behavior

Gitlab does not redirect back to mattermost after authentication.

from the gitlab i found out.
