I’m using ngrok for creating SSH tunnel. I tried connecting to it in firefox but I get open failed: connect failed: nodename nor servname provided, or not known in terminal after going to a random website.

I connect to ssh using ssh -D 127.0.0.1:8080 <username>@0.tcp.ngrok.io -p 17817 and configure firefox like this:
Firefox network configuration.
But when I go to whatismyip.com, my ip does not change and I get channel <channel number>: open failed: connect failed: nodename nor servname provided, or not known. I tried opening ssh connection by doing ssh -p 17817 <username>@0.tcp.ngrok.io and configuring firefox with 0.tcp.ngrok.io for SOCKS Host and 17817 for port but I got Unable to connect message. I spent more than 2 hours trying to fix it and nothing worked. All ssh tutorials say that I should be able to connect.
