Access behind PFSense->HAProxy for nextcloud app

[foxhoundv]

I have a docker server setup behind PFSense and HAProxy to handle my subdomains. On PFSense it rewrites http to https but internally it communicates via port 80 so that way my internals don't need a self signed cert.I am using this git with a twist, I added a mariadb image to the compose file because I prefer it that way to keep that traffic internal to this docker stack. I am including a link to the walkthrough I created for others that may want that option so you can see how the setup is.

Docker + Nextcloud + OnlyOffice + MariaDB

I can access everything just fine from a webpage, even my computer Nextcloud program syncs and works fine. However both Nextcloud and OnlyOffice apps on my Andoid phone (11) won't work. OnlyOffice says, "SSL handshake error" and Nextcloud says, "Unknown error occured!"

I don't know if there is a special setting that I need to do for the NGINX image or maybe something else.

I am by no means a programmer, I can read code and kind of get the idea of what it's doing but when it comes to creating anything and syntax, I am a total noob.

If you want to check it you can go to my nextcloud here.

I hope I'm not the only one having issues connecting via apps.
