If you have been confronted with this error code, we likely identified your ISP as one where a lot of abuse comes from and blocked requests to prevent attacks. If you encounter this issue, please submit a ticket to our help desk at https://windscribe.com/support/ticket and provide us with the first 3 numbers of the IP value you get from your ISP.
You can check what your IP address is here: https://ipinfo.io/
As an example, if your IP address is 100.115.92.14 then please send us the first 3 octets which would look like this: 100.115.92. This way you are not actually giving us your whole IP.
We will make an adjustment and then get back to you.
