Issues with setup

So I have two servers running nextcloud and i have a reverse proxy server running upfront.

I need the reverse proxy to convert HTTP to HTTPS and point the correct domain to the correct server. So I have the following:

nextcloud.domainx.com = local ip: 192.168.4.21
nextcloud.domainy.com = local ip: 192.168.4.22

Config on REVERSE PROXY

https://hastebin.com/woyesukace.nginx

This configuration works for nextcloud.domainx.com but when I try it for nextcloud.domainy.com it gives me “Internal Server Error”

DomainY Nextcloud NGiNX Error Log:

https://hastebin.com/ibexiwayeh.error

What am I doing wrong?

Hi,
if you get a 50x error, this looks like an issue with the second nextcloud server.
Given the last errors logs, looks like the nextcloud instance setup failed.
Check folder permissions.
Regards.
Aal.
