I am trying to secure a self-hosted GitLab solution using Cloudflare zero trust. I followed their tutorial but when adding the DNS record I get 'This hostname is not covered by a certificate'. but I ignored it since the tutorial doesn't mention anything about HTTPS, and they even configure the ingress to work on HTTP.
When I try entering my website after finishing the configuration I get 'SSL_ERROR_NO_CYPHER_OVERLAP' I tried multiple browsers and tried adding let's encrypt certificate but it didn't help.
Did they omit something in their tutorial? or am I doing something wrong?
