How to fix CodenameOne build upload error

Question

I have been running into some issues when trying to submit a build to the server. Every time I try to submit it, it fails. Here's the output of the process :

Please help me out !

In 9 times out of 10 it means you ran out of build credits for this month which are reset every month. Notice that you can see those in the subscription tab.

In 9 times out of the remainder this is due to a bad connection/proxy configuration. You need to configure the Java proxy as well as the main process.

In the last 1 percent of the cases something might have went wrong in which case I suggest contacting us via one of our support channels.
