Thank you.
From wireshark, it says “Communication Administratively Filtered”. Per RFC, This generally means an ACL, Firewall or Router on the path from client to server (alpha) is filtering the communication and sending this code
See
Things to do:
1 . You may want to check the Firewall, ACL settings on your client.
2. Maybe try a different client.
3. Take a tracepath/traceroute.
Hope this helps.
