Check if the error occurs in other versions, as you are trying to use mods, the best thing to do is contact the CurseForge forum where they can help you better.

You need to contact your Internet provider about problems with your Internet connection

, i try to connect my XBOX one by WIFI & get this ERROR: "your security protocol will not work xbox one "Your console supports WPA/WPA2 (personal), WPA2 (personal), and WEP network security protocols, but your router is using something else.
You'll need to change your routers configuration.""

Hello, LostProdigy422

Since you are using the Wifi at a public place, there may be firewall blocking incoming and outgoing connections to Xbox Live. You will have to ask the network administrator at the hotel to open some ports to your internet connection.

Ask the network administrator to open -

On Xbox 360:

Port 3074 and set the protocol to Both

Port 53 and set the protocol to Both.

Port 80 and set the protocol to TCP

Port 88 and set the protocol to UDP

On Xbox One:

Port 3074 and set the protocol on Both

Port 53 and set the protocol on Both

Port 80 and set the protocol on TCP

Port 88 and set the protocol on UDP

Port 500 and set the protocol on UDP

Port 3544 and set the protocol on UDP

Port 4500 and set the protocol on UDP

Hope this helps your issue.
