Good morning @kakarlayogitha,
Thank you for contacting Octopus support and sorry you are having issues with connecting an external GitLab feed.
We do have some documentation on setting up a GitHub feed if you have not seen it yet that may help? GitLab works differently and we do not have any specific documentation on setting this kind of feed up.
A few things I have noticed from your screenshot that may be worth mentioning.
In our documentation for the GitHub feed you are supposed to set the URL to an API endpoint as described below:
So I think you would need to set that URL to https://gitlab.example.com/api/v4/ (this is what it suggests in their documentation) rather than your direct feed URL which is what I imagine you have put in that URL field.
Are you also using a Personal Access Token for your credentials? If not we recommend you set one up and use that, there is some documentation on Gitlab here for how to do this.
Hopefully implementing those changes helps but please let us know if it doesn’t.
Anything else you need in the meantime please feel free to reach out.
