Suddently captchas switch from numbers to text strings? How to prevent?
In general I am using the re-capturing feature which challenges the user for (short) numbers.
This works normally. But sometimes suddenly after e.g.7 number prompts the prompt mode seems to switch to text patterns. It is still the same series of parts for the same download. It is still the same uploader. I did not touch JDownload itself before. So what is the reason? I could imagine that the problem comes from heavy CPU usage due to other tasks (e.g. compilations) but I am not sure. Is it because of server problems? When I exit JDownloader and restart it later (e.g. after an hour) then everything is fine again (=numbers are prompted). How can I prevent this nasty switch to text pattern captchas? Peter |

Google changes Recaptcha from Easy to Middle to Hard when they detect you as an bot There are many factors fors that...Captchas/Domain. Number of Captchas/Time. Captchas/IP. SolveTime.....this has nothing to do with JDownloader, totally up to Google/Recaptcha what captcha style they provide you.
You can enable Browser Captcha Loop (for easier RecaptchaV1) and RecaptchaV2 are all done within your browser. There is nothing we can do about this

I had the browser loop timeout constantly causing hard captchas. It had everything to do with high CPU and memory loading- JD itself was using 70% of the combined CPUs and over 2GB RAM. Problem went away entirely when I doubled my computer's RAM.
I also found that using Chrome as the browser loop browser cause the captchas to get hard over time on SOME RCv1 sites but not all. Switching it back to Firefox stopped that, though it causes other usability problems. |

I suggest to use Firefox, because Chrome sends more *data to home*
Browser Loop should not have any affects on memory usage, maybe the browser does not close/stay open. I'm sorry but there is nothing we(JDownloader) can do about this.
