I have run the Chrome connectivity test. 

The only failing test is "Google websites could not be properly retrieved and loaded."

All the other tests pass. These include connectivity, firewall, dns, delays etc..

Attached is the log.

The incognito mode brings the same issue.

Can you collect a net-internals trace?

@ sal.barba: Gentle ping, Can you please update the details as requested in comment#3.

Just tried on a non corp network and able to navigate to gmail.com on Windows 10, Mac 10.12.6 and Linux OS (Ubuntu 14.04) using chrome version 61.0.3163.49 Beta build.

Thanks.!

Do you know if you're running a proxy/firewall product on your network? Some products have known issues that interfere with newer version of TLS.

In addition to collecting a net-internals trace, can you go to chrome://flags/#tls13-variant and set it to "Enabled (Experiment)" and see whether your connection works again, that should work around the issues with the Fortinet software, while still allowing more secure forms of TLS to be negotiated.

Hello, 

1) the net-internals trace log is attached 
2) the issue started immediately after the mcafee live safe update, no change were made to corporate proxy-firewall in that time frame (about 15 minutes), and the issue arised immediately after the computer restarted. So the interference is with mcafee not with the corporate proxy-firewall.
3) I have set the chrome://flags/#tls13-variant to "Enabled (Experiment)" and now the connection to gmail works again. 

Thanky you for the help and for this workaround. I hope that the log file helps to understand what is going on. If I need to do more testing, let me know.

That's good to know, thank you.

We're doing experiments to figure out which variant is most compatible with broken middleboxes/VPNs/firewalls, so additional data that Experiment is working it is useful. If you have a chance, can you test whether the other ones (RecordType and NoSessionID) work, but otherwise you can leave it on "Enabled (Experiment)" and I'll close out the bug in a couple days.

I have tried again only with gmail, although I found a couple more sites that loaded partially I didn't remember which they were, so I cannot reproduce them. However, the gmail is the most significant indeed.

RecordType: works fine
NoSessionID: same error ERR_SSL_VERSION_INTERFERENCE

I have set it back to "Enabled (Experiment)"

Thanks

Thanks for the additional information. Leaving it at Enabled (Experiment) should be fine then.
