Using Nextcloud under Subfolder (i.e under domain.com/nextcloud)

[wwe]

hi @Mystic welcome to the community

it’s hard to say if you passed the required parameters in your .env file… but in general running Nextcloud behind reverse proxy and non-webroot requires additional configurations. Please review

• 101: reverse proxy
• overwritewebroot
• reverse proxy

Docker image accepts ENV variables to setup above configurations

• Docker community image/reverse proxy

good search term in the forum are reverseproxy nginx webroot.

Starting new installation from scratch is maybe not easy please review this advanced installation examples:
docker-compose-setup-with-notify-push-2024
Nextcloud docker compose setup with Caddy (2024)
