I need you to run command line, from the commandline this command:

nslookup t1.gstatic.com

a then cut’n’paste the results for me - and three times, for t1, t2, t3.

Also check the hosts file for any records regarding this.
It’s usually in c:\windows\system32\drivers\etc

Third thing is to check out which dns servers do you use.
Running cmdline again, and this command:
ipconfig /all

and then cut’n’paste your dns servers.

I suspect you’ll have there 188.229.88.7 or 188.229.88.8.
