Default J-Downloader - randomly breaking, long response-time

Hello,

first of all thank you for this wonderfull program that i use now more than 10 years! Keep up the good work.

Now to my problem at hand.
Since a few months my jdownloader2 behaves weird. I want to download something, so I start jdownloader, now I copy my links, which should transfer to the linkgrabber and here the problem starts. The popup will come and stuck at status: checking online, this might work after a few minutes, but most of the time it wont. It also doesn't matter which host it is (Rapidgater, Click'n'load, real-debrid etc). When i do a system restart it works, but anything short of a system reboot so far didn't fix this. I assume everyone can understand not wanting to do a full system reboot every time we to add links into jdownloader.

So i tried a reinstall (with and without config). I even scrubbed every peace of the jd2 before reinstalling. Still the same problem.

Even more, once this sets in, it isn't just the linkgrabber. I tried to add my accounts, and had the same problem. For example real-debrid:
After putting in my credentials, it took a few minutes for the browser popup to show where i could confirm that i want to add this device, and another few minutes after i confirmed to get the feedback from the jd2. Same with other hosts eg. Mega.

Jdownloader2 information:

jd2 current build Nov 26.
Java Temurin - OpenJDK Runtime Environment - 1.8.0_322

Logs from after reinstall with the weird behavior (normal logs, if emergency ones are need i will update):
26.11.22 16.01.56 <--> 26.11.22 15.29.28 jdlog://0541311370661/

System:
Windows 10 21H2 build 19044.2251

Firewall: Basic not configured Windows Firewall

AV:
Malwarebytes
Used Browser: Firefox and chrome - current build


Anybody an idea that would do the trick?

@Teradi: change Settings->Advanced Settings->InternetConnectionSettings.preferredipversion to IPV4_IPV6 and restart JDownloader

Issue is caused by non working IPv6 connectivity.
JDownloader first tries IPV6 because your OS signals valid IPv6 connection and fails with connection timeout

1:api.real-debrid.com/2a10:13c0:ef1c:0:0:0:0:10:443|java.net.SocketTimeoutException(connect timed out)|retrySSL:null
That takes a few seconds before the timeout happens and JDownloader tries working IPv4 next

You might wanna check your setup ,why it has a valid IPv6 but seems not to work properly. You can check it with
ipv6-test.com
