New ContributorUpdated Blaster Not Working
The cause of the problem was found. It was the frequency of the USB Blaster.
The Quartus II software comes with drivers for the USB Blaster, but does not allow for changing the communication speed of the Blaster.
The Quartus Prime software does. The default value of the speed is 24 MHz, and the devices we were trying to program worked at a lower frequency. Once we changed the frequency of the USB Blaster to match the devices, it worked fine.
New ContributorI too facing this issue.
If your Pc is connecting to the Internet through a gateway on the local network, you should repeat these steps on the gateway too. If you still cannot send, there may be some problem on DNS autonatic recognition then you may have to manually enter your DNS address:
In SendBlaster "Send" form, manually enter your DNS server IP address (ask your Internet Service Provider if you don't know its address).
If these steps don't help, your Internet Service Provider is likely to be blocking direct delivery (port 53, 25 or both): this is a policy adopted by some large providers such as AOL, and unfortunately there is nothing you can do about it (apart from changing your provider…).).
