Nextcloud version (eg, 20.0.5): 27.1.2
Operating system and version (eg, Ubuntu 20.04): Ubunut 22.04
Apache or nginx version (eg, Apache 2.4.25): not sure, on System is apache 2.4.52 installed but i use also an Nginx Proxy Manager and have no idea how the communication here works
PHP version (eg, 7.4): 8.2.11
Since a few days i have the problem that i can´t connect to my Nextcloud via domain or IP-Adress in my Home Network. If i try to reach Nextcloud from outside of my home network, for example with my mobile Internet connection, everything works as it should, at least as long my server had a connection to the internet. For now i took it off the internet because i don´t know whats going on here. The errors i get are ERR_SSL_PROTOCOL_ERROR, when i try to connect to nextcloud with a vpn and NET::ERR_CERT_AUTHORITY_INVALID without a vpn. These errors still exist after i put the server down. A little research points out that there maybe is a man in the middle attack, thats why i put the server down. The SSL Certificate i get shown with these errors in the web browser are not installed by myself. I can see this cause i use lets encrypt Certificates for Nextcloud and they have a time limit of 90 days, but the shown SSL Certificate is valid till 2038. Also when i try to connect to nextcloud via intern IP-Adress i get ERR_SSL_PROTOCOL_ERROR. I tried all i can find on the internet to solve ssl errors like delete Certificates, timeset etc. But the shown certificate, which comes with the error, i couldn´t find anywhere till now to delete it.
Also my Router gives me “The DNS rebind protection of your Router rejected your request for security reasons.” when i try to reach my domain/subdomain name.
So i need help to get rid of this errors and connection to my nexcloud again.
Is this the first time you’ve seen this error? (Y/N): Y
