Problem with Activating Chipless Firmware
Disable firewall and proxy
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 okay or is there perhaps an alternative approach to activate based on the ID code?
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.
Checking Network Connection
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.
Resolving Communication Issue
Good day. I apologize, provided port number was incorrect, actual port is 20102, I tested it right now and was able to connect.
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,
Good day. It is working at the present moment.
My order 193493 Keyless firmware for Epson XP 960. I've got error code 10060 communication error. My printer USB connect with the PC is no problem. Please help.
Server Issue and Resolution
We had server issue. Try now.
Hello, I've bought an activation key for my WF-3720 but I can't activate the chipless firmware. I'm getting the error message: CHANGE USB PORT. CHECK NETWORK CONNECTION, MAKE SURE THAT PROXY IS NOT USED AND DISABLE FIREWALL. TRY AGAIN LATER. 10060. I've checked the internet connection and I can't reach the server. I've also tried another internet connection but the same error. Is there someone who can help me with activating my WF-3720 chipless firmware? Is the server online and reachable? Kind regards, Kenneth.
Solution for Blocked Server
Chipless server is blocked by something on your side it may be antivirus/firewall on PC or firewall on router or even internet service provider. You can check software on PC and router setting, but if it is provider then you need to use VPN for activation (there are plenty of free ones on the web).
Any suggestions for a free VPN that I could use?
Resolution with VPN
All right the problem is fixed I have used https://windscribe.com/ as a VPN tool and tested the telnet command and bingo! It was the internet provider that was blocking the connection. Thank you for your suggestions!
