Setting up assetto server help!

[htrhtrthr]

I’m trying to setup a assetto server but I have spectrum and sadly using there router so I have to use there phone app to do port forwarding

9600-udp and tcp

8081- udp and tcp
I don’t have a option for http

I’m able to see the server in sever list. But it show ('internal error: sending request')

Is it not possible to set a server up on a spectrum router? or is my brain just really smooth
