I have a vm in azure from where i connect to different vm in my azure subscription using point to site connection.
i have vnet gateways for all those vms.
suddenly my vpn connection stopped and giving error like :
"The connection was prevented because of a policy configured on your RAS/VPN server.
Specifically, the authentication method used by the server to verify your username and password may not match the authentication method
configured in your connection profile. Please contact the Administrator of the RAS server and notify them of this error. (Error 812)"
i could connect to other vnet gateways and vms. but could not connect some vms under one vne and gateway, i am getting above message for them.
All vms are 2012R2.
please help
