I have a few users who have trouble with any google based website while using Firefox. We suspect this is an issue with a specific setting in InterceptX but we can't pin it down. The site loads sometimes, other times it breaks in the middle of using it (youtube). Or won't load at all and just tries and tries (google.com and gmail.com). This is extremely frustrating for our users who are affected. Does anyone have any suggestions? The only difference I can see is that on the machines affected the policy uses the "Beta" versions of the newest definitions. I am unsure how to turn that off, and would gladly try if it meant fixing this irritating intermittent issue.
Ok, after some investigation I found how to remove my machine from the "EAP" (Early Access Program). To do so:
I will test this out to see if it fixes the issue and report back.
Hi Josh, I have the same issue on some Windows 10 machines using Firefox and open Google-Urls.
Any new hints from your test? I checked the "Early Access Program" but it is not configured for any machines.
Any other ideas to fix this issue? Looks like this problem is a temporary one.
When I turn off the Sophos, the googles urls will work
Hello Pascal, unfortunately I don't have any new information. For us the issue resolved within a little while of removing clients from the EAP. Literally hasn't come back a single time! One suggestion I would make is to be sure your Sophos AV client and if you have a Sophos XG firewall like we do, is updated to the latest firmware 18.5.3 (maintenance release).
If you are seeing the URL's work when you turn off Sophos AV, I suspect you have those same definitions we had from the EAP. Maybe they have made their way into the general release of Sophos AV? I also recommend updating Firefox to the latest version on the affected machines. Best of luck sorry this is happening!
Seeing the issue here aswell, Override policy for 4 hours and turning off "Real time scan internet" appears to be the work around.... anyone had any additional insights?
I'm seeing this same problem too on a Macbook Pro running Bootcamp. I have found that while working remotely over VPN the problem does not occur. When I'm on the LAN where the heartbeat is active, the problem occurs repeatedly. I've tried cleaning up Firefox, turning off InterceptX for a period, changing which connection I'm using - nothing works. My suspicion is the heartbeat is having an effect since that is not present when my machine is off the LAN. We don't have EAP turned on.
This problem does NOT occur while running MacOS and Firefox. It only occurs under Windows on the LAN.
I've been experiencing this issue for about 2 months now, disabling Sophos "Web Control" and "Internet" Real time scanning fixes the issue for me, Just have to disable it every 4 hours.
I found the solution to this.
"This could be a problem with the TLS 1.3 Early Data feature also known as Zero Round Trip Time Resumption (0rtt). You can try to set security.tls.enable_0rtt_data = false on the about:config page to disable this feature until this is fixed by Google or Mozilla to see if that helps."
I implemented the solution above, but the issue maintain. On gmail tool the message as the print below presents after 5 minutes. I got the same error using whatsapp web, when the messages not updated after 5 minutes on the tool. When I close firefox and reopen all tools come to work again, but 5 minutes later the same problem occurs.
Console from Firefox

Anybody could help ?
If you open this website in inkognito mode within the faulty time, does it work by refreshing the site?
