Fresh Install - No Certificate generated for domains other than traefik proxy?

[aasimenator]

Hello everyone,

I’ve deployed OpenCloud using the deployment folder and the .env file without making manual changes to the docker-compose.yml or Traefik configs (since everything is supposed to be read directly from .env).

Main domain (proxy.xyz.com) is working correctly with a valid certificate from Let’s Encrypt.

Other subdomains (drive.xyz.com, office.xyz.com, wopi.xyz.com) are not receiving the correct certificate. Instead, they are showing the Traefik Default Certificate. "net::ERR_CERT_AUTHORITY_INVALID - Subject: TRAEFIK DEFAULT CERT"

✅ DNS for all domains/subdomains is properly configured and pointing to the correct server.
✅ No errors are showing in the container logs (Traefik, collabora, etc.).
❌ The issue is specifically that only the main proxy domain gets the Let’s Encrypt certificate, while the others fallback to the default Traefik cert.

Has anyone faced this issue before? Do I need to configure anything extra in .env (like explicitly listing subdomains for Traefik/LE) or should the deployment auto-handle subdomains as long as DNS is correct?

Any guidance would be appreciated.

Thanks in advance,
Aasim
