Hi there,

i am trying to install Nextcloud AIO on a debian system with an apache reverse proxy where port 8080 is already used by another docker container.

what do i need to change to run the nextcloud AIO container?

docker: Error response from daemon: driver failed programming external connectivity on endpoint nextcloud-aio-mastercontainer (4a4b0135de2945f97330a7488d69e567cc9eae347f55e3ad1e022b1dbdbc1dd1): Error starting userland proxy: listen tcp4 0.0.0.0:8080: bind: address already in use.

but leaving out the 8080 part in the docker startupt (–publish 8080:8080 \ )
i cannot access nextcloud.

this is my apache site:
