Hi All, I have weird issue in Firefox when trying to connect to websocket server on xenserver(xcp-ng to be exact) it seems firefox for some reason is unable to make the connection the error message is very poor as it does not explain the cause why firefox is not able to make the connection. the error message just say "Firefox can’t establish a connection to the server at wss://" I tried to enable logging and check the logs , it was not easy to understand I suspect there is a disconnect but not sure the same code and same site works perfectly in chrome and it works on older Firefox versions but on the latest versions it does not work I dont know when exactly (what version it stopped working) but last tested version that worked is I have the logs of 2 cases first case is full log from our website while i am trying to connect to the websocket from or site second case is just i opened the site and from console I wrote new WebSocket('wss://...',binary) will upload it shortly Thanks
