I installed Collabora Online using Nextclouds own instructions. It’s online, I’ve checked docker status, it shows online, and I’ve checked nc and it shows it’s open on that port. But still when I try to use it in Nextcloud it tells me it can’t connect.
Nextcloud log error below:
[richdocuments] Error: GuzzleHttp\Exception\ServerException: Server error: `GET https://mydomain.com/hosting/discovery` resulted in a `502 Proxy Error` response:
