[Solved] ouo.io captcha not loaded

[lezboyd]

When I copy a ouo.io (or ouo.press) link to JD2, it transfer me to the captcha page on the browser, but the captcha is not loaded within the page. It works fine on the ouo.io site itself, but not with JD2. Here is a screenshot for the same, and some example links.



JD links (maybe the ID numbers will help?):
**External links are only visible to Support Staff****External links are only visible to Support Staff**
**External links are only visible to Support Staff****External links are only visible to Support Staff**

Actual links:
**External links are only visible to Support Staff****External links are only visible to Support Staff**

ouo.io uses recaptchav2 which is provided opened in your browser via 'browser solver'. Since it works fine here, it's most likely something todo with your browser setup. maybe noscript? please check our support article https://support.jdownloader.org/Know...splay-captchas

which browser do you use?

I use Firefox and have no scripting related add-ons installed which may block captchas. Captcha solving works fine everywhere else. The only place I face this problem is JD2.

[raztoki]

as you can see we use localhost, many of those type of browser extensions are known to block it. check the trouble shooting section of the support article.

I did check the article before I replied.

1. None of the advanced settings have been changed.
2. Localhost is excluded in adblock.
3. No other extensions are installed that mess with scripting.
4. My country does not block google.

Maybe if you are unable to help, you can let someone other support personnel reply to this? I shall co-operate fully from my side. But lets not run around in circles.

Thanks.

Would been nice of you to state that in your previous post instead of just a screen shot (I believed you that it worked in browser for the website itself). I responded on the assumption that you possibly hadn't. This is in no means circles.

I would recommend that you open inspect element and goto the network and|or adblock tabs, refresh the JD captcha challenge and see what happens. You can also breakpoint the javascript components if you have that type of experience/understanding.

Please check the line I wrote above the screenshot. I will paste it again for you:

"I use Firefox and have no scripting related add-ons installed which may block captchas. Captcha solving works fine everywhere else. The only place I face this problem is JD2."

I shall do the "open inspect element" part and get back. If that does not pinpoint the problem, can/will you assist with the "breakpoint" part?

The captcha portion is giving an error while loading from the JD2 generated page. Pasting the same below:

java.lang.NullPointerException

yes I read the line, but it didn't indicate either way if you had looked at settings/document. I read it as you don't have no script like addon installed/running.

I'm heading out for the day, I will be available this evening if you still need assistance.

the Java exception pasted is useful,
the code in question

             String refOrg = request.getRequestHeaders().get("Referer").getValue();

do you prevent referrer information within your browser by any chance?

raztoki

[raztoki]

I'm back for a couple hours, just installed a chrome extension (chrome doesn't have native feature) which allows you to block/filter/change referer. I ran a test, with referrer blocked and I get the exact same exception as you. So I assume that you run some referrer blocking function within your browser settings or extension.

raztoki

[lezboyd]

Thanks for the reply. I checked the referer settings in my Firefox browser, and its not turned off.

network.http.sendRefererHeader;2

Are there any other settings I should check in about:config?

[raztoki]

just confirm that is the case via the inspect element within network tab.
only reason that jd throwing that exception is its returning null/missing.

Please wait for next core update and try again

[raztoki]

I also made localised changes, but I was going to ask coalado the importance of that code before committing

[lezboyd]

Thanks Jiaz, confirmed as solved.

@Lezboyd
Did you find out what was messing with the referrer info ? Id be some what concerned if you haven't

[Jiaz]

Thanks for the feedback!
