Collabora Apache reverse proxy not working and other issues

Nextcloud version: 16.0.1
Operating system and version: Ubuntu 18.04
Apache version: 2.4.29
PHP version: 7.2.17

I’m trying to set up Collabora but have hit a roadblock that I think has to do with the apache reverse proxy. I’m running everything through Docker containers on a server running Ubuntu 18.04. For containers, I have one for my webserver running apache2 and letsencrypt, one for my nextcloud server which is reversed proxied through the webserver container. I then have another one for the Collabora server. I have a FQDN and I have nextcloud going through nextcloud.mysite.com and colloabora through collabora.mysite.com (A records). I can’t access collabora through collabora.mysite.com, I can only go though using https://127.0.0.1:9980. I can log into the admin panel if I do it through localhost or if I type in my servers ip:9980; when I go though https://collabora.mysite.com it points me to the /var/www/html folder on my webserver container. https://collabora.mysite.com:9980 just gives me an error saying the service in unavailable.

Below is a copy of my collabora.mysite.com.conf. I’ve tried many combinations following https://www.collaboraoffice.com/code/apache-reverse-proxy/, so I’ve tied it with the commented out sections active as well. I’ve also tried to replace 127.0.0.1 with the IP to my server and the IP of the collabora container, but each time is still points to the root of my webserver.

I was able to get collabora working for a bit if I set the collabora server to my serverIP:9980 and diabled certificate verification. It stopped working though and I now get the following error
