"An established connection was aborted by the software in your host machine"

Postby staraptor78 » Wed Jan 01, 2020 3:06 pm

Hi Everyone,

I'm doing a data transformation using Clover DX and i'm experiencing the below response error when running my graph:

Code: Select all

Caused by: java.io.IOException: An established connection was aborted by the software in your host machine
   at sun.nio.ch.SocketDispatcher.writev0(Native Method)
   at sun.nio.ch.SocketDispatcher.writev(SocketDispatcher.java:55)
   at sun.nio.ch.IOUtil.write(IOUtil.java:148)
   at sun.nio.ch.SocketChannelImpl.write(SocketChannelImpl.java:504)
   at org.eclipse.jetty.io.ChannelEndPoint.flush(ChannelEndPoint.java:263)
   ... 88 more


Anyone familiar with the aforementioned error and how do i fix it? I've attached my graph for further reference, it's not that complex and i'm running clover on a fairly fast PC if ever you consider that as a factor

Hi Staraptor78,

Thank you for reaching out. Based on the snippet of the stack-trace, the most likely cause of this error is your firewall. Since CloverDX Designer and CloverDX Runtime communicate with each other over TCP on localhost, the port they use could've potentially been blocked by the firewall thus aborting the connection. If I am right, adding a firewall rule for CloverDX Designer might help. Give this a try and please inform me of the outcome. I look forward to hearing from you.

Best Regards,

Hi @Dahrveng,

Thanks for the response. I only had the spare time today to test your fix. Unfortunately, i'm stll getting the "host machine" error. I've already added an inbound firewall rule in my machine. You may refer to the screenshot I attached. Both the CloverDX executable file and the java binaries have firewall rules.

Thanks,
