irst ofall , i have rb1100 with public IP x.x.x.x so i upgrade the rb and set user manager as i read it in wiki of mikrotik and i did these steps
1-set ip on ether2 =192.168.1.1/24
2-make a pool " 192.168.1.10-192.168.1.254"
3- activate DHCP server on ether2
4- add DNS
5-add router 0.0.0.0/24
6- add nat - masquerade
7- add user profile in hotspot
8-add server profile in hotspot and check on " use radius"
9-add server of hotspot
10-add radius server with IP public and do it with IP 127.0.0.1 and do it with 192.168.1.1 same problem and check on hotspot and add secret
11-enable radius incoming with port 1700
12-open user manager on browser with public ip and on router add public IP with same secret i added on radius
13- add profile
14- add users
so when i connect to the router always tell me radius server is not responding and i dont know why so any idea what the problem is?
