If by "server does not respond" you mean the FreeRADIUS server then maybe you should consult with the FreeRADIUS-Users mailing list.

You're welcome to continue asking here for help too, but probably you should provide us with some debug log of FreeRADIUS when it receives the authentication requests packets so we can see whats happening (the FR-Users ML guys will ask you for this too).

Also, congrats on working with daloRADIUS :)
