MX 17.8 firmware and Radius issue

We have a setup where several remote MX device have SSIDs with Radius authentication to two servers (one through Meraki site to site VPN and another directly to a public ip). They were working fine under 16.x firmware but once upgraded to 17.x firmware 801.x authentications are no longer working (SSID with normal preshared keys continue to work). If I downgrade the device back to 16.x it will work fine again. Opening a ticket with Cisco support just say that this is not a know issue and they will have to troubleshoot over a live session. I already had issue with 17.7 earlier and had to download. This happens again on 17.8 released very recently. Anyone else have similar issue or it's just me?

Do a packet capture on the RADIUS packets.

 

I bet the source IP address the packets are coming from has changed.

I have the same issue.  Betting it is using the wrong interface to send the RADIUS packets.  I have a case opened and they saw the radius packets being sent but no reply.
