Image Slider widget Displaying Error 520 on browser

I'm getting a weird error warning, when I want to view my form in the browser. It's on the place where a Image Slider should appear. Is the Widget not working? Thanks for help.

Hi,

Upon checking your account, it seems that the image slider is now working fine.

Is this the form you are referring to that has the widget?

The problem might be a temporary hiccup on the widget's server. You can also trying clearing your form's cache just to make sure.

Let us know if you are still having problems or if I'm pointing on a different form.

Thank you.

Thanks for the hint with the cache! Unfortunately it didn't fix the problem. In the meantime I figured out, that the problem is a loading problem.

The widget (Image Slider) in my form (it's a different one) is hidden behind a password protection and is only showen when a checkbox is filled. Could this be the problem???

Hi,

May I know what form you are referring to? I'm unable to find that form, a form URL or ID would help us. Also, is it embedded on a website?

Regarding the condition, if you set a condition to show the image slider, you don't need to hide the field as this will make a conflict. The image slider should not be displayed when the condition is not met.

Here is my sample condition.

The image slider does not need to be hidden, it automatically does that when condition is not met. Here's my sample form: http://form.jotformpro.com/form/43145017169957 

I hope this works. We'll wait for your response.

Thank you.
