thank you for all the details. I don’t see any issue with your config (especially no reason why CODE → Nextcloud doesn’t work with https and works with http). you are using #cloudflare - some of their security and optimization options are known to brake things e.g. JS compression - consult [GitHub - nextcloud/all-in-one: 📦 The official Nextcloud installation method. Provides easy deployment and maintenance with most features included in this one Nextcloud instance.](https://github.com/nextcloud/all-in-one#notes-on-cloudflare-proxytunnel) for details

but maybe

added to traefik.yml will help already..

PS: this is definitely not **the** problem and I don’t know if you have a reason to do so but in general you don’t need fixed IP with docker.. _usually_ you can skip all the `ipv4_address: 192.168.xx.yy` directives
