Hi all,
is there any detailed tutorial about how new captcha system works on JD2?
like which setting does what on captcha settings window, timeouts etc...

I have an issue with uplodable.ch :
when i start a download, it repeatedly sends captcha to captcha brotherhood, captchas are solved correctly, but download doesn't start.
First it sends captcha to CBH, JD2 gui doesn't show related window (which shows that captcha is sent to CBH), then after about 20 secs, it sends another captcha for the same download, again no gui is displayed, then after about another 20 secs, same thing happens again, still no gui. after several captchas like this, JD2 starts to show gui when captcha is sent to CBH, but same loop continues with captcha solved but download doesnt start, which causes users to lose captcha exchange system credits without any downloads. by the way, captchas are really difficult to solve.

when i try same link with browser, it shows a readable captcha, but doesn't start download when i solve captcha, it says something like "your ip submitted many wrong captchas, please try again later"

about this, i would suggest
- somehow, users should be able to set JD2 to stop sending captchas from a hoster to CES systems, after X failed download from that hoster, for Y minutes
- about captcha settings window, priority settings, users can put methods in order of their preffered priority, and give each method a timeout to finish its own work. so they put one number for each method, which may be more readable for users.

Please see: 'settings > captchas'
It gives you control over which solver gets used sequence, and timeouts values are all possible to set at this given time.

I would recommend that you post logs from such a session so we can see what caused the underlying issue with uploaded.ch. I'd suspect that uploadable has server issues ('file server < socket issue > you' and JD retries.)

captcha image quality for recaptcha v1 has vastly increased when you use browser loop or google.com (recapthca) account in the account manager. Please see https://board.jdownloader.org/showthread.php?t=63148 for more information and support article, https://support.jdownloader.org/inde...splay-captchas. At this given time RecaptchaV2 can only be solved in Browser solver, also mentioned in those last two URLs.

We will be soon adding more control to the core over captcha types and management of those, but this is not for CES reasons mentioned here. /
