We had the same NO-PROPOSAL-CHOSEN error on the remote side of the Site to Site VPN. We have found that with Load Balancing enabled and Active-Active AutoVPN set to Enabled, the Non-Meraki VPN peers can still only be established on whatever interface is set as the Primary uplink on the SD-WAN & Traffic shaping page. We resolved the NO-PROPOSAL-CHOSEN error by using the correct Public IP of the MX on the remote side of the tunnel.

I have confirmed that all AP's are in the same subnet. All of their IP's are static and are added to ISE for authentication

Hi Blake. The AP's are all added to an ISE with all Users' credentials. This issue is intermittent. There will be a lot of successful connections to an AP and then sometimes a user would fail to connect. This happens at random with random users in the network and random AP's. I have not been able to replicate the issue with a specific user or a specific AP.

Good day everyone I have some users on my Wireless LAN that are failing to connect to an SSID. This SSID is open with only Radius authentication. The building is quite a dense Wireless network with a lot of AP's. 802.11r is enabled on the AP's as well. The error code when looking from the Network Wide > Clients > Roaming point of view is: Failed connection to SSID (x) on AP (x) during association When looking at the Meraki logs, the error code is as follows: auth_mode='wpa2-802.1x' 11k='1' 11v='1' ft='1' reassoc='1' error_code='55' radio='1' vap='0' channel='100' rssi='51' Does anybody know what the cause of this error code might be? I have looked through all documentation and I can't find anything on error code 55. Thanks in advance Etienne
