On my self hosted gitlab-ce I set up a webpage with a custom domain www.example.com pointing (CNAME) to my namespace.mygitlab.com webpage. After selecting the automatic certificate management a message gets displayed
GitLab is obtaining a Let’s Encrypt SSL certificate for this domain. This process can take some time. Please try again later.
but even after waiting a few days, nothing happens and no certificate gets issued.
What is the problem and where do I start to debug this issue?
The log with gitlab-ctl tail gitlab-pages says

what does this mean and what could possibly go wrong?
Thanks for any directions
