I cant connect to any Minecraft servers
Solution 1:
First try to relaunch Minecraft. That would fix a timeout issue. If that doesn't work try to restart your router. That could reset any firewalls. If that also dosn't work try to uninstall and reinstall Minecraft. I've had a problem once where a firewall was randomly set up so try to call your Internet Service Provider and see if there are any fire walls up. If all of this fails try Mojang Support.
