Tunnel breaks web-app that is HTTP and the end result is HTTPS

Dear all ,

I am quite new to this , I am sorry if this was already asked and I didn’t find it.

I have a device that has a webserver that operates on a HTTP port.

When I pass it though a free tunnel , it breaks everything. Nothing works nor loads.

There was some online discussion to force the tunnel to operate in HTTP , BUT I couldn’t find anything on the settings in my existing tunnel.

I would very much appreciate the help ,

Thank you in advance
