Problems opening Gmail

[L u c a s]

Hi everyone, I've got a problem. I can't open Gmail on any browser. I've tried safari, google chrome and firefox to no avail, so I know it isn't a problem with Safari. This is the error message I get:

All other Google sites work (search, youtube, etc.) I've tried it on other computer accounts, and it works, but for some reason not on mine. Let me know if I can provide anything else.

Thanks!

Is port 443 open on your firewall? What are your current SMS settings? Can you get to any other HTTPS sites?

For the first two questions: I don't know, how do I check? (Sorry if I sound like an idiot, it might be because I am ) For the last question, I might, but I can't find another example.

No, other https sites will not work. The same error message appears.

Has this suddenly happened ? Was it working fine yesterday and broken today ?

Who is your ISP ?

Yeah, it happened all of a sudden, but not today. I think this started on Thursday

You need to go into your router settings and see what ports are closed down. Have you made any changes or added any new components to your network recently?

You can learn about and test your firewall ports at GRC's website for Shield's Up.
