Hello,
My cutomer try to activate my EXE file and get this error:
windows 7 and this is the excel version
when I try to activate the same file it works.
Please fast, if possible.
Thank you !
Support, please help.
Thank you.
This error means that the EXE cannot reach the server of your customer. Maybe a firewall is blocking the outgoing connection? Anyway, there is nothing you can do on your side. Or give him an offline activation key.
how can he open the firewall blocking ?
What is the name of their firewall?
Ok, new customer right now gets the same error.
It is not possible that 2 customers gets the same error one after the other, and before that I never got this error…
Please tell me what to do…
Then, please double-check that your server is working. Maybe you can review the server log (if any), ask your customers for their IP address and see whether the log contains connection attempts.
I think I found a solution, so maybe it will help to others…
It works with one customer (i didnt try it with the second customer yet).
the problem is TLS 1.1/2 :
https://support.microsoft.com/en-gb/help/3140245/update-to-enable-tls-1-1-and-tls-1-2-as-default-secure-protocols-in-wi
in the middle of the page there is a download button, after running this fix file and restart the computer, it works.
Is this fix makes sense to you ? i mean is the XLS padlock using TLS 1.1/2 ?
I will try it with the second customer and let you know.
Yes, that would make sense since TLS 1.0 (and even 1.1) is being dropped:
Maybe your server was recently configured to handle TLS 1.2 only?
