Describe the problem
Custom domain shows Active/verified in Reverse Proxy Custom Domains, but any service on it stays stuck at “Issuing certificate…” forever on NetBird Cloud (free plan, eu1 cluster). The built-in free domain on the same cluster issues its certificate instantly. This is not self-hosted.
To Reproduce
Steps to reproduce the behavior:
- Add custom domain mohandl3g.ly under Reverse Proxy, Custom Domains.
- Add wildcard CNAME *.mohandl3g.ly to eu1.netbird.services in Cloudflare, DNS-only (grey cloud).
- Click Verify Domain, and wait for status to become Active.
- Create a reverse proxy service for example jellyfin.mohandl3g.ly.
- Service stays at “Issuing certificate…” for hours; opening the URL shows the “certificate not issued” error.
Expected behavior
The proxy should automatically issue a Let’s Encrypt certificate via ACME (tls-alpn-01 on port 443) and the service should become Active.
