Hi, I just tried it again, but got the same issue using port 20102 as you mentioned. It's again stuck after sending the syn package to the port at IP 211.159.168.205. My firewall is deactivated and communication to other ips works fine. Could you please verify that the server is still up? Thank you,

Maybe I was too late by just doing my test today, but I had no success using telnet on my machine as well as on my mobile using 2 different ISPs (normal fiber + mobile phone company via 4G). No firewalls were active for the test and I also tried it additionally via a VPN provider to ensure no ISP filtering happens. C:\>telnet 211.159.168.205 63429 Connecting To 211.159.168.205...Could not open connection to the host, on port 63429: Connect failed Looking at my TCP viewer I can clearly see that a SYN package was sent, but nothing is coming back (SYN/ACK is missing) as the 2nd step for a TCP handshake. In all cases I simply get a connection timeout, which makes me feel that might be an issue with the remote server not wanting to talk to me rather than a problem on my end.

Hi John, The firmware update went through as expected, but I just ran into that communication error as well (despite of disabling the firewall on my end and testing 2 different USB ports). Just in case it matters, I have a Epson WF PRO 4720 and used the firmware from https://chiplesssolutions.com/download/WF4730_FWF475TL_CM23I5.zip for my update. My order number is #15964616. Are your servers ok or is there perhaps an alternative approach to activate based on the ID code?
