Hi friends.

There are some servers that only let me download 2 files at a time, if I try to download more than 2 files one of them will fail and try again in 10 minutes (this is normal).

How can I reduce the cooldown from 10 minutes to 1 minute or less? Here is an example:



Thanks in advance.

Thank you so much, this really solved the problem, thanks again!

Thanks for your feedback.

May I ask which website you were downloading from where that issue kept happening again and again?

Sorry for the delay in replying, I just saw the message now.

Sure! I was downloading several files from **External links are only visible to Support Staff****External links are only visible to Support Staff**, with the JDownloader SmutBase plugin set to download from the US server:



Apparently this website only allows downloading a few files at a time and won't download the next one until one of the active downloads finishes, which is why the JDownloader countdown appears (or so I think).

@nicknick: Can you please provide a debug log, see https://support.jdownloader.org/de/k...d-session-logs
Enable Debug Mode, restart JDownloader, reproduce the issue and then create log. Then we can check and update limits in JDownloader to avoid this error

[pspzockerscene]

In my tests, the error was unrelated to the current amount of open connections.
Lowering the wait time for all users is not the solution here.
Example which kept failing:

smutba.se/project/file/download/90525/us/

(By the time someone else tries this one, it may just work.)

Error in browser:

ERR_EMPTY_RESPONSE

JD:

java.io.EOFException: empty HTTP-Response

Sure, I did the test again with 10 links to replicate the problem, here you go:

17.12.24 18.20.14 <--> 17.12.24 18.22.24 jdlog://3647411370661/

Oh, so there might be a solution? That would be great, I always thought it was a download server limitation or something.

Thanks again to both of you for your help!

Your logs contain exactly the same problem that I encountered during testing.

So just to be absolutely clear:
The problem is that smutba.se is sending an invalid/empty response instead of the file(s), seemingly randomly.

The solution can be either to try again later (well, this is all JDownloader can do) or to contact the smutba.se support and ask them to fix their server side problems.
Feel free to pick your choice but this issue is not a JDownloader problem/bug.

@nicknick: to me this looks like either server side issues and connection handler dies (eg too many connections) or very bad implemented rate limiting (as it just drops the connection). I would just contact the site about this, maybe it's on purpose , maybe not

Thank you both very much for all your help. Previously, the 'ams1' server allowed infinite parallel downloads, and the 'us' server did not.

Now neither of the 2 allow more than 3 or 4 parallel downloads, so I think it's on purpose and not a bug. I mean, premium registered users do have infinite parallel downloads and faster speeds, so it's not a bug.

So now I know it's not a JDownloader problem and you can slowly download multiple links at the same time (reducing the retry time).

I know the admin on Discord but I'd rather not bother him about this since it seems he was on purpose about free users and it's really not a problem, so thanks again to both of you for your help, you two really are the best! <3 :D

When knowing if this is caused by request rate or number of concurrent requests, we could update internal limits to avoid this or at least reduce it happening. maybe worth a quick chat...like..."hi..how are you doing...did you saw movie xy....ah btw...what limits have you setup in web server* :p
