Captive port detected in Zscaler

When ever we are connected to that Corporate Wi-Fi, ZCC is throwing an error as “Captive Portal Detected”. we went through all the troubleshooting and configuration but still its throwing captive portal error popup

I would open a ticket with Zscaler support. Sounds like they need to look through the logs to determine what the issue is.

As mentioned, I think a support ticket here is a good approach. This thread might help a bit as well.

I performed this search here that might help as well in some troubleshooting and fact-finding.
