Local server on raspberry, admin and app on web

… ehm. I have the same problem as this guy

Use reverse proxy in front of blynk local server

Hello, I start a docker with blynk server on it, to acces to the admin i create a reverse proxy (Caddy) who generate ssl certificate automatically. https://blynk.mydns.org { proxy / https://blynk-docker:9443 { websocket insecure_skip_verify transparent } gzip timeouts 300s proxyprotocol 0.0.0.0/0 log / stdout "{hostonly} - {combined}" } I have access to the admin interface, but for some strange reason the app wont connect to my server and tell me: Something went wrong…

He tried both 443 and 9443 with no success.

Maybe you are right that the problem is no blynk specific!
But hope …
