Google Drive grays out with "Unable To Connect" error after computer idles

I was having the same problem, a simple work around is to quit google drive. Then follow this path "C:\Program Files\Google\Drive\googledrivesync.exe"

If you can't find google drive sync, go to your main drive and enter it in the built in search engine.

Don't forget to create a desktop shortcut if this becomes a recurring problem.

This isn't Exactly A fix For your Issue as your ISP is Partially to Blame but i can show you a little bit of a work around and show you how to make a basic script to force refresh google drive i hope it help (Windows vista-10)

Step One: Right click and create a new .txt file

Step Two: Open the New txt file an type the following line (Make Corrections as need)

@Echo Off

taskkill /F /IM googledrivesync.exe

Start /min "googledrivesync.exe"

exit

Step Three: Save the file as a .bat or .cmd to the location that contains your googledrivesync.exe.

Step Four: Create A shortcut or keybind (or anything else of your preference linking to the file.) and run it any time google disconnects

NOTE: You can Corrupt files "IF" they are in the "MIDDLE" of sync it's "UNCOMMON" as google is very good about handling files but force refreshing Programs can cause negative effects they are few and far between and often very uncommon but "YOU HAVE BEEN WARNED!" don't blame me if you just start rapid refreshing in the middle of an upload to see what it does.

I've experienced a similar problem with google drive on Linux, if my internet interface is turned off, google drive will lose it's connection, and when the interface is turned back on, google drive remains "unable to connect" until restarted.

It's possible that one of your power-saving options may be set to disable your network when the computer is "idle". While this normally wouldn't affect anything, as when you start moving the mouse it should automatically reconnect instantly, this could cause some programs to lose connectivity while idle.

Google drive seems to have difficulty re-connecting when the interface itself is disconnected from the internet, and then re-connected.

Perhaps you should take a close look at all of your power settings and make sure that windows isn't set to "disable network interface when computer is idle", as I know that has been an option on most network interface settings in the past, and certain versions of windows have it enabled by default.
