Cannot connect to Steam network
Steam games are really popular and many users use it to play many games.
But sometimes it gives you an error saying "cannot connect to the steam network" when you try to login to steam. This does not happen normally but when it happens it is really hard to get connected.
When you log in, steam creates some file inside the "appcache" folder and it is the reason you are unable to connect to the steam network.
To resolve this simply, delete the "appcache" folder and login again.
Now you will be able to login without any errors.
