I’m having trouble accessing my nextcloud from outside after a power outage.
Everything was working fine until the power went out at home and when it came back, and I started my server, I can access my nextcloud from the monitor correctly, but from the internet, outside my LAN, there is no access.
I have turned the server off and on several times.
I have restarted apache2 and mariadb.
I have checked that the ports are open with ufw
I have checked the configuration files and everything is correct, and I have also casually looked at the SSL certificates.
My nextcloud installation is NOT on Docker, but directly on the hard drive on debian 11.
Sorry, thought that with blablabla.ups you meant your (obscured) hostname which you use to reach your nextcloud instance from the internet. Can you please with the real one (do not post it). For example via DNS Lookup Tool - DNS Tools - MxToolbox.
Good to hear it is working again. Best thing would be to update your address automatically via a DDNS client or via your router (not all routers have this though). In this way it does not matter when your IP address changes (for example during a reboot of the router).
