kenny1983 0 Report post Posted August 11, 2020 Hello, I've bought and 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 a other 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 Share this post Link to post Share on other sites
wic.support 21 Report post Posted August 11, 2020 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).

It was the internet provider that was blocking the connection. Thank you for your suggestions! Share this post Link to post Share on other sites
