Issues with hotel and airport WiFi

Hi,

Need specific versions of the OS and Endpoint install to answer this.

Hi Richard, it will be agent 10.0.4 and most likely the OS will be Big Sur, We're still trying to gather more information but it means sending a technician to one of the sites with WiFi where its not working.

The only thing I can think is that Sophos is seeing the redirect to the captive portal as something malicious?  But nothing shows in the events page.

Is there any vpn products installed and active on the system?

No, they are fairly generic MacOS builds with just Chrome and Office added to them. From what I understand, this happens in both Safari and Chrome. 

okay, I think this will probably need more indepth investigation than I can do over the forum. I would suggest you open a support case and gather the following:

1) a SDU from one or more affected machines

2) a TCPDump while the issue is happening

3) a TCPDump while the issue isn't happening (turn off the parts product if needed)

I think the issue is with the WIFI having a landing page that is getting blocked or not presented - probably because it has an untrusted cert - but I can't be sure without the above.
