Clients connected to the Guest network cannot access Internet

WLAN is set to guest, VLAN is set to virtual controller Managed, Client VLAN Assignment is set to default, there are no restrictions. I reset all of the access points which didn't help. Can anyone think of any troubleshooting steps or places to look? No recent changes were made to the network. 

 

Clients that connect to the guest SSID get a 172.31.98.XXX ip address . Their network status shows connected. If I have the user disconnect or forget the guest network and reconnect they get the 172 ip address again but still cannot connect to anything.

Client traffic that is Virtual Controller Assigned get source-natted out of the ip address of the AP that is the Virtual Controller.  If that ip address can get to the internet, your guests should be able to, as well.  If that ip address is blocked from the internet, your guests will not be able to go to the internet, either.

Do you know how I can check this?

You can try SSH into the Virtual Controller and try pinging 8.8.8.8.  What is your path to the internet?

Pining to 8.8.8.8 may be blocked by the firewall policy .

better you can check with security team to debug traffic source from your  controller ip . then you will come to know traffic is blocking in firewall level
