Hi,

I try to connect a payment terminal in odoo 14 in module POS. I well setted the ip of the terminal and work fine in local.

But when I try to connect it in production behind nginx (https) I get the following error:

Mixed Content: The page at 'https://mysite.com/pos/web?config_id=1#cids=1' was loaded over HTTPS, but attempted to connect to the insecure WebSocket endpoint 'ws://192.168.8.100/SIXml'. This request has been blocked; this endpoint must be available over WSS.

I tried to add reverse proxy nginx to force wss but don't find the solution...

If someone have idea to help me in this task I will be verry happy.

Thanks.
