Nextcloud version: 20.0.3
Operating system and version: Raspbian Buster

PHP version: 7.3.25
The issue you are facing:
I can not get caldav or carddav working while trying to use proxy_pass from my reverse proxy. I have tried many different configurations. My url does redirect to what the docs say it should (https://domain.com/remote.php), when trying to reach https://domain.com/.well-known/caldav. I am not receiving an error inside of nextcloud.
There is nothing of relevance in the nextcloud log but I can share if need be.
The output of your config.php file in /path/to/nextcloud (make sure you remove any identifiable information!):
