[solved] Can’t login to Syncthing GUI with Ngnix Proxy Manager

Edit: Solution is in Nginx I disabled these: Cache Assets, Block Common Exploits, Websockets Support.

I can login using the local IP 192.168.1.2:9101, but when I route that with Nginx, It won't.

I have the GUI listen address as : 0.0.0.0:9101

I've been googling for hours but I can't find anything, In browser console it says

Failed to load resource: the server responded with a status of 403 ()

syncthing.my.domain.com/:1  Refused to execute script from 'https://syncthing.my.domain.com/meta.js' because its MIME type ('text/plain') is not executable, and strict MIME type checking is enabled.

Can you post the syncthing logs, as well as the nginx logs?

I assume you've seen this: https://stackoverflow.com/questions/48626459/refused-to-execute-script-because-strict-mime-type-checking-is-enabled

Can you post your nginx config? Is it just this one with different variables? https://docs.syncthing.net/users/reverseproxy.html
- I'm using the Web GUI Nginx Proxy Manager https://nginxproxymanager.com/
  
  I tried to add what's in the docs.syncthing using the GUI but it failed, I wasn't sure if I should modify something inside the ngnix docker container or not.
  
  I'd definitely take a look at the syncthing logs...
  
  The log doesn't mention anything regarding a login attempt
  
  403 Forbidden doesn't necessarily mean a bad login attempt. Are you sure that's the error? My troubleshooting steps would be to access directly (no nginx), and look at the logs for a successful login. Then, look try to login with nginx, and look at those logs (both access.log and error.log on nginx, and any/all logs from syncthing). Find out where the two cases diverge and go from there.
  
  Does syncthing have a domain name specified? If it doesn't know its domain name it may work from IP directly but not via reverse proxy. Just a hunch.
  
  In Syncthing logs the difference between success and fail
  
  Success

  Fail

  Does syncthing have a domain name specified I can't find an option to do so
  
  This suggests nginx options to use re: hostname. Unsure of your nginx config...

  I managed to get it to work finally, I disabled these Cache Assets, Block Common Exploits, Websockets Support.
