Hi, i am currently implementing webauth with Cisco ISE for self register, but i am having issue coa. I was able to get non-windows machine to work but with windows i can't push out the url redirection through coa. I have enabled debug and i can see ISE trying to push out the url redirection to the port, however the url was not show when i issue a show authentication session interface gi 1/0/x command. The only issue i can see from the debugging is that the interface failed authorization first then a success authorization right after. Again, the url redirection work on non-windows machine, i have even go as far as disable dot1x supplicant on windows and it still didnt fix the issue.
please see attachment for the debugging i had mention above. If anyone know or had this issue before please let me know how i can resolve this.
