The easiest way to access your application from another device is to enable the "reverse tunnel"
which gives you access to your application via
If you have an error that looks like:
client connect error: dial tcp xx.xx.xx.xx:12345: connectex: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.
It could be that either your firewall OR your router is blocking the connection to the reverse tunnel server.
Make sure that your router is not blocking the connection.
