Sophos Captive Portal re-authenticating users when roaming to different Unifi Access Points

Hi Temidayo Abayomi-Zannu

Just wondering same setup was working earlier and stopped working now?

Regards

Hello,
We started utilizing the captive portal about a month ago due to the site being a factor and multiple known/unknown users connecting to the network.

We did have this set up at a similar location and the same issue still occurs.

Now users with Apple devices are complaining that the Captive portal pages isn't opening anymore and they are getting this error.

I'll reach out to Sophos Support regarding this as suggested.

Can you share current setting under CONFIGURE-->Authentication-->Web authentication-->Captive portal behavior ? with screenshot ?

Did you allow DNS service on any Zone without restriction ? Post the firewall rule if yes 

Regards

Yes i did as seen in the image below.

Good day,
The captive portal details are listed below.

DNS route was also created. The captive portal does work but am currently experiencing 2 major issues.

• Users get disconnected and have to re-authenticate via the Captive Portal.
• IOS users sometimes get the error message as shown in the prior image.

Regards.

For tshoot keep DNS rule as below without any policy applied 

 From iOS device,Press the “I” next to the wifi name, go to “configure DNS”, change it from automatic to manual, and type “8.8.8.4” into the DNS server if you have dns locally hosted set the same DNS and try for troubleshoot.

Good day,
Apologies for the late reply. I had been troubleshooting the issue with Sophos support.

We were able to push out the SFOS v20.0.1 MR-1 firmware update and noticed that the issue seemed to have been resolved.
I tested this at a similar site and the results were the same.

It seems they have patched the issue in the latest firmware. Please note that the controller and switches weren't updated.
Thanks everyone for the support.
