Radius Server Not Responding

Hi All,

i read too many posts regarding this issue but none solve my problem.

i’m working on RB 951G-2HnD. running as HOTSPOT Server for 20 users, using MIKROTIK USER MANAGER RADIUS Server.

everything was working well before upgrading to the latest version 6.30, now each time i am trying to use a voucher that created by MIKROTIK Userman it gives me RADIUS Server Responding.

how can i solve this issue asap.

It seems either this problem has no solution or no one know anything.
