I've been wrecking my head trying to get my 90& self-hosted life online and it's going great so far, except for Nextcloud.
I've set up several passes in nginx before, all working perfectly fine after a little tweaking, but despite trying out multiple ways to set this up I get 1 of 2 errors every time.
1. I get a 502 bad gateway most often.
2. I get an internal server error and the url looking like this https://cloud.domain.com/nextcloudnextcloudnextcloudnextcloudnextcloudnextcloudnextcloudnextcloudnextcloudnextcloudnextcloudnextcloudnextcloudnextcloudnextcloudnextcloudnextcloudnextcloudnextcloud
Here is the relevant part of my nginx file:

And my most recent log file after attempting to set it up (mostly useless, due to the obvious URL issue):

and here https://github.com/ReinerNippes/nextcloud you find a working ansible playbook to setup this config. saves you some typing. 
I’ve attempted to use that one, and it does correctly solve the recursive url issue. But it does have the issue with 502 bad gateway that I’ve been unsuccessful in solving as well 
Thanks for your reply and time btw!
it looks like you didn’t configure memcache/redis.
and i think it’s better to use the unix socket connection to connect to php. the path and name of php7.x-fpm.sock socket depends on your linux/installation.
I’ve attempted to follow your guide, and everything checks out. Except that it stills recurses the url to nextcloudnextcloudnextcloud… and so on.
Any idea what might cause that specific issue?
sorry. no idea.
if you try to setup nextcloud on a vps you may want to try one of my playbooks. they will setup everything for you.
