Summary of the issue you are facing:
Hello,
I have the problem that I can’t access nextcloud from my local network with the domain I have. I get net::ERR_CERT_AUTHORITY_INVALID. From outside it works fine and the cert is valid (letsencrypt).
I get NOT the letsencypt cert locally. And it does not matter which device I use ( there are at least 5 different ones). I can reach nc from the local ip and the public ip address with the correct cert (but https is crossed out).
I also don’t have that much network experience so excuse anything that might be wrong or obvious.
Gemini said it is a network issue and I should set dns-rebind on my fritzbox. I did it but it did not helped. I also set a different dns server (v4 and v6) which also did not help. Also I did add my domain to dns-rebind after I got this issue. It worked beforehand without it.
If I do nslookup I got the public IP Address (which is good gemini says).
Thank you for your help.
Steps to replicate it (hint: details matter!):
- connect to wifi
- got my.domain.tld
- see the cert error and got the wrong cert
