I have ubuntu 16.04 laptop, And I want to ssh it from a different network. my router is tp-link AC750. I enabled port forwarding, as in the image enter image description here

I found my public ip address using google and tried to login remotely, but not working. How can I troubleshoot this?

I modified to port 2222. now getting the following error while trying to connect:

debug1: key_load_public: No such file or directory

debug1: identity file /home/mobaxterm/.ssh/id_rsa type -1

When firing up ssh, use -v flag for verbose output. You can then clearly see what exactly went wrong.

Might be a silly question but: do you have an sshd (like openssh-server) running on your laptop? I ask because it is not installed by default.

try with another port on external, many routers don't forward external 22 (also 80, 443). try with eg 2222 forward to 22 on your computer and you MUST test it outside your router network, you can't test it from internal. of course like @PerlDuck said, check if your destination is listening on port 22 from all networks netstat -anutp grep :22 to check.
