python - Socket.close() doesn't close the Socket -

i'm trying develop simple client/server program, server part working i've problem client part can't understand why.

the client's work simple, retrive counter value external device, i'm trying send retrieved data server part.

at beginning socket working well, time when should send data i've got server exception , after client not working.

i can't understand if s.close() function working properly.

update: exception got "errno 110 connection timed out"

client:
