App Proxy with TLS not working

[dominikjannis]

Hi everyone,
i am trying to set up the new App Proxy with TLS, but struggle to do so. The app I want to proxy through Cloudron runs on a DO droplet behind a Caddy reverse proxy, no domain is attached and a self signed certificate is installed. The app is reachable from the web. When setting up the App Proxy in Cloudron with https://<IP>:443, it does not start, stays on starting for a while and then switches to not responding...
Am i missing something here?
Any help is appreciated!

@dominikjannis Can you tell us which version of Cloudron you are on? We fixed a number of App Proxy related issues in 7.3.2 . Can you update to 7.3.2 if that's not what you are running?

@girish thanks for your response! I was running 7.3.1. So i updated and recreated the setup now with 7.3.2, now the App Proxy proceeds into running, but still does not serve the app.
Here some things i tried and observed:

• when using a self signed cert for usage with the IP, it serves a blank page
• when using a public domain with an LE cert, it responds an nginx 502
• The app is reachable from the public internet in both cases with TLS when adressing it directly
• The Cloudron Health check reaches Caddy on the target host every 10 sec. with status 301

@dominikjannis Do you think you can send me the IP address to support@cloudron.io ? I can test it out from my test instance.
