After update to NC15, NC server redirrect access attempts to local IPv6
Access is made this way:
- client connect to subdomain
- ports 80 and 443 are forwarded from box/modem-router to front apache server
- apache serve client by internally proxypass requests to NC server using it’s local IP
Nextcloud version : 15.0.2
Operating system and version : Debian 10
Apache or nginx version : Apache 2.4.25
PHP version : 7.0
The issue you are facing:
Is this the first time you’ve seen this error? : Yes
Steps to replicate it:
- Having a front server working as web server with proxypass and proxypass reverse (same config as NC) and another web server with NC 14.0.6 on it
- using apache to proxify sub.domain.tld to NC server using local IP (eg: 192.168.1.12)
- adding sub.domain.tld as trusted domains and working with it
- updating NC to 15.0.2

I’d like to add that this configuration worked well up until the update from NC14 to NC15.
And since someone’s may ask for it, here’s the front server’s apache config:
