I'm not sure if this is the same problem BUT it's a good place to start. Verify the time on the NAC and your web controllers, make sure you have your SNTP set properly and there's no variation between all the devices.

Also look at this article: https://gtacknowledge.extremenetworks.com/articles/Solution/NAC-End-Systems-Hung-in-Captive-Portal

Also, be sure that you have NAC ip addresses in the ip-helper addresses for the BYOD/guest vlan interface.

I met similar issue with both EWC and NAC-GW (Identity Access Engine) sitting on the same vSwitch on the same VMware hosts. The communication from Qtrunk portgroup to non-qtrunkg portgroup was dropping packets heavily. this issue was fixed in new version of VMware.

good luck
