Domoticz behind Nginx reverse proxy

Hi all,
I placed my Domoticz installation behind an Nginx revers proxy to create secure connections with SSL. All is working well, except the powermonitor.
When I access my Domoticz webpage via the proxy, the Powermonitor doesnt show reallife information, but I have to refresh the page manually.
If i access Domoticz via the internal IP, all is working well.
Could someone help me with this?
Thanks in advance!

Thanks for your reply!
Yes, i have done that!
I am using the Nginx proxymanager, maybe there is a problem?

What do you mean with "the Powermonitor doesnt show reallife information"?
I do not know a Powermonitor page/device. I know the Utility page where all the Utility devices are listed.
Are the devices on other pages like temperature and weather updating correctly?
If you press F12 (inspect) in the browser with the "Powermonitor" webpage do you see errors in the console?

Goodevening!
I indeed mean the utilities page. They show the correct information, but I have to manually refresh the page to update the information. This goes for all pages.
I'll check the error console!
Update: It says a websocket connection has failed.

Can you clear your browser cache? See wiki for instructions for your browser.

Your tip did the trick! I just needed to enable websockets. Thanks for your help!

Hi @gwabber.
I have also domoticz behind reverse proxy and I'm getting wss errors in my web browser:
Code: Select all
WebSocket connection to 'wss://domoticz.mydomain/json' failed:
NPM log:
Code: Select all
[07/Jun/2022:12:47:26 +0000] - 400 400 - GET https domoticz.mydomain "/json" [Client 12.34.56.78] [Length 89] [Gzip -] [Sent-to 192.168.0.154] "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/...
Can you explain how did you manage this to work? Which config file I need to modify? How did you "enabled the websockets"? Am I using APACHE proxy or NGINX proxy? I'm totally lost now
I'm using NGINX proxy manager and Cloudflare. Both NPM and domoticz are in docker containers.
I have also tried to modify NPM host config, but without luck.
FYI: Domoticz page is loading OK, but these websocket errors are causing error 400 (bad request) constantly and my fail2ban is banning me all the times

Hey @majki,
I wish I could help you, but I use the Nginx reverse proxymanager webinterface and I just turned websockets on in the settings menu:
