Since good solutions have always been suggested here, I’ll try it again today.
I have set up a reverse proxy with Apache Nextcloud
I have the following error message
The reverse proxy header configuration is incorrect or accesses Nextcloud through a trusted proxy. The is not the fall, then it’s a safety problem, also the attacker allowed the IP address, the for nextcloud visible is to hide. Further information can be found in the documentation.
What do they mean and how do I fix this error
Reverse Proxy and Nextcloud Server are two different PCs and are installed on the Reverse Proxy.
