Hi Anyone, have found any workaround for this issue we have the same problem with Iphone 13 IOS 15.2.1 "After this iphone keeps sending NULL data frames to the WiFi router for which it keeps responding and it goes on for next 45 seconds." There is a consistent delay of 45 seconds in the display of the splash page. With android devices or IOS version 14.X there is no problem.

Same problem here, send me and email

Hi @jegankarthick, I wonder if you have any advanced with the issue on captive portals. From this side we have a consistent delay of 45 seconds since the iphone try to reach the domain of the page, until it is push by the Apple Push Notification Service on the iphone. I suspect that is because my portal is only in http, in the capture of wired shark I can see that there is communication between the Iphone and some Apple IP's (17.57.144.27) with TLSv1.3 format. Maybe the Iphone try to reach the domain in https with SSL certificate, because it does not exist after the 42 seconds opens the http format by the APN service.

Hi @jegankarthick, yes how can I share the wiredshark captures with you?
