If you've just received a notification and you've got the error, it obviously doesn't mean that you have an issue with your internet connection. And if you've just received a notification it also means that the server is up and running. So, what is going on?

One possible reason of this error is a too short timeout, in that case you can try again after incrementing the timeouts:

• Open the application (if not already done)
• Click on the Menu button.
• Select the Preferences.
• Scroll down to Server connection timeout and select it.
• Increment the current value (if it is 5, then enter 6).
• Scroll down to Data timeout and select it.
• Increment the current value (if it is 3, then enter 4).

In the case of this specific error, it is important to increase the Data timeout. You can try incrementing the value multiple times. If you still have the same issue, contact me.

Yes, since the 2.0 release it is possible to use Llama to setup the notifications configuration. To do so follow these steps:

• In the action selection menu, choose "Run App Shortcut".
• Select "jdCaptcha Shortcuts".
• Select the operation to execute (see the list of shortcuts below).

There is one main settings that could cause this behavior. Follow these steps to check the main settings:

• From the home screen, click on the Menu button.
• Then click on Settings to go to the settings screen.
• Click on the section Accounts and sync.
• Make sure the Background data is checked. If this setting is not checked (not enabled) the application won't work.

When you try to register your device to your account you have an error message even if the username and the password were correct.

Change your password on your account and try again. Sometimes some password are not working well during the registration. Once the device is registered you can change again the password.

Yes, to do so delete the jdCaptcha plugin directory and then install the new version.

Follow these steps:

• Go to the My Account section of the website.
• Make sure the box 'Receive captcha notifications' is checked.
• Go in the jdCaptcha plugin directory.
• Open the jacinfo.xml file with you favorite editor.
• Locate the line '<command ... >' and remember the value of the 'src' element.
• Copy the input.jpg file to the 'src' value seen in the previous step (example cp input.jpg input-0.jpg).
• Execute the jdCaptcha script (jdCaptcha file or jdCaptcha.bat file).
• You should receive a notification on your phone, resolve the captcha.

Check these few things:

• Make sure the checkbox 'Receive captcha notifications' is checked.
• Check that the plugin is working (see the related question in the plugin section).
• If you have the captchatrader plugin installed on jDownloader you should remove it.

The captcha notifications are notifications sent to your phone to tell you that you have captchas to solve.

If you don't enable the captcha notifications you'll not be alerted of new captcha to resolve and your jDownloader tool will not get the result.

The other notifications are a "big" word to say everything but captcha notifications. Currently, other notifications are:

• Account approved.
• Test notification (available in the My Account page).

If you don't enable the other notifications, you'll not be able to test the application (test notification) and you'll not receive a notification when your account will be approved (an email will be sent).

No, you can't. If you want to use jdCaptcha on more than one device, you should create as many account as devices.

Starting from the version 5.0 you will be able to create a community to send the captcha to one of your device.

Here are few things you can check:

• Verify the email address you've provided.
• Verify the spam box.
• Change your email address.

Generally accounts are approved within 24 hours. You can speed up the process and even approve your account automatically by following these "rules":

• Validate your email address (check also your spam box). If you do not validate your email address your account will not be approved.
• Register your device. If you do not plan to use the application but only the email notification, check the Receive captcha notifications (through email) box (stop here and wait for the approval).
• Check the Receive captcha notifications.

To approve your account by yourself:

• Check the Receive other notifications.
• Click on Send a test notification. If you successfully receive the test notification your account will be approved.

The jdCaptcha application is not compatible with iPhone. It uses Google services such as the Android Market (which is not available on iPhone).

Yes since the 2.0 release it is possible to also use captchatrader.com but you need to install the PHP version of the jdCaptcha plugin.

To enable the captchatrader.com feature, unzip the captchatrader archive in the jdCaptcha plugin directory (you should have a new directory in the jdCaptcha directory). Then download the captchatrader patch here and unzip it in the jdCaptcha directory.

Your captchas will be sent to captchatrader.com when you disable the captcha notification.

That's because every time a notification is sent users are not necessarily ready to respond (they could be asleep or just doing something else).

It doesn't mean that jdCaptcha is not working properly.
