Challenge failed for domain

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help.

My domain is:

Hi @wilcore22

is the webroot path correct?

Create the two subdirectories


there a file (file name 1234 without extension), then try to load that file via

or use online tools to check that complete url.

That should work.

Hi @JuergenAuer
Yes, the path is correct because that is the root of gitlab, create the 1234 file, and load correctly with https, but with http it does not load.

I can see the http version -

/.well-known/acme-challenge/1234 works, same directory with a random file name has the expected result http status 404 - Not Found.

Visible Content: 404 The page could not be found or you don't have permission to view it. The resource that you are attempting to access does not exist or you don't have the necessary permissions to view it. Make sure the address is correct and that the page hasn't moved. Please contact your GitLab administrator if you think this is a mistake. Go back

I'm not so firm with these GitLab - pages. Isn't there a specialized tool to create Letsencrypt - certificates?

Hello, I could solve it, the problem is that cerbot must load with port 80, so the nginx that has gitlab was reconfigured without ports and the external_url that had https was removed, additionally the firewall was configured so that the server where there was the gitlab, I had access to port 80, with that I executed the command and it worked, thanks.
