Hey there.

This can often happen on local machines when anti-virus software gettings in the way (trying to inspect .jar or .zip files). Could that be happening here? What happens if you manually call from a browser (or curl it to your local machine?)

I am able to download the file. Moreover I am using dedicated Ubuntu machine with no antivirus installed. Any workaround possible to locally fetch the .jar file without downloading every time? If that solves the issue. And adding to that the jar file takes lots of time to download as well.

How long does it take to download the file on this machine? The file is 20 MB.

About 30 mins. My network connection is working well with other servers/sites. No VPN(s) are up as well.

Majorly getting 30-40KBps speed.

As mentioned: Any workaround possible along with the downloaded file.

Some Progress after waiting like 30 mins:

Now again it got stuck.

I think this issue is due to server bandwidth. I was able to finish the scan after a long time. Post that the scanner runs smooth.
