Help! fault diagnosis test message Connection

(sorry my English is very basic)
Hi , I can not receive diagnostic test menasje Connection with Avast. I get the same message:
Refers to:

  1. Connect wifi (is correct)
  2. port 5228 (do not think that is the problem)
  3. old Avast version (I have latest version).

I updated Avast several times, and there is no way …
Any idea to solve the little problem?

My phone is a Samsung Galaxy SIII 16gb

Greetings to all and thanks in advance :wink:
