I have following problem:
JDownloader have a JDRemote Plugin, this is a simple Webserver.
On my Android phone i have build a app who sends HTT Posts to the JDRemote Plugin.
After some posts, JDownloader runs in a loop because the connection is resetting.
The best thing to do is to stop the shields inside avast! one at a time and then try your connection - this way you can quickly isolate the shield causing the problem. You can then add the exclusion in that individual shield. (Remember to restart the shields again afterwards!)
