About VCS Integration method

I tried to VCS Integration GitLab (CE) with Terraform Cloud.
I proceeded according to the official manual below, but when I clicked “Continue” after entering the GitLab Application ID and Secret in step 3, I got a 404 error and could not proceed.

■ Official manual

Since GitLab limits access by IP address, I think that is the cause, but is there a way to publish or know the IP address on the Terraform Cloud side?

Thank you.

Hi, welcome to the forum!

There is indeed; you can get information about Terraform Cloud IP Ranges here.

Thank you for your valuable information.
It seems that this will proceed.
