Facing issue to Taiga Setup with Gitlab OAuth login

Troubleshooting Self hosted Taiga
1

Hello,

We are planning to use Taiga self hosting solution for our organization. We are already using GitLab self hosting solution running on hxxps://gitlab.domain.com.

We could host Taiga using Taiga 30min Setup and it works fine on hxxps://taiga.domain.com.

As per documentation, Add to &default-back-environment environments

ENABLE_GITLAB_AUTH: "True"
GITLAB_API_CLIENT_ID: "dad548xxxxxxxxx"
GITLAB_API_CLIENT_SECRET: "gloas-95d2e42xxxxxx"
GITLAB_URL: "hxxps://gitlab.domain.com"
PUBLIC_REGISTER_ENABLED: "True"

Add to taiga-front service environments

ENABLE_GITLAB_AUTH: "true"
GITLAB_CLIENT_ID: "dad548xxxxxxxxx"
GITLAB_URL: "hxxps://gitlab.domain.com"
PUBLIC_REGISTER_ENABLED: "true"

We created “Taiga-Authentication” application as an Admin user and generated application id and secret key.

Callback URL: hxxps://taiga.domain.com/login
Trusted	: Yes
Confidential: Yes
Scopes: All

After user press signup with GitLab, it could login to GitLab and comeback to Taiga but getting below error message.

“Our Oompa Loompas have not been able to get you credentials from GitLab.”

Once we open “Network” in “Inspect Element”,
Request URL: https://taiga.domain.com/api/v1/auth
Request Method: POST
Status Code: 500 Internal Server Error
Response: {“error”: “Server application error”}.

Please consider “hxxps” as “https” in my above messages. We are looking forward your response.

Regards,
Neel

Hi there,

Have you checked taiga-back logs during the request?

Best regards!

Hi, Neel,

It seems there that the issue is when sending the registration email. Your instance cannot access the email host you provided.

Best regards!
