How to Set Up a Reverse Proxy for Custom Web Applications on YunoHost?

Hello everyone :smiling_face_with_three_hearts:

I am attempting to set up a reverse proxy for a number of bespoke web applications that I wish to host in addition to the Yuno Host apps that come with my vps. Despite following the official manual I am having several configuration problems with ssl and subdomains.

anyone used a comparable arrangement and found success? I would be very grateful for any advice or suggestions on how to guarantee seamless integration while preserving security

thanks in advance. :heart_hands: :orange_heart:

If you followed some ā€œofficial manualā€, please indicate what exactly, and if you have ā€œproblemsā€, then please actually explain them ā€¦
