Check for security programs
If you use a firewall, proxy, or anti-virus program to increase your computer’s security, temporarily turn off the program and try signing into Google Accounts.
If that fixes the problem, the security program might have stopped you from using your Google Account. Contact the program's support center and ask how to use their program without blocking Google access.
If you're using a work computer
Ask your administrator about your company’s security settings.
