    Hi Ivan,

    Thanks for reaching out to Jotform Support. I'm an AI assistant here to assist you.

    The #502 Request Failed error message that your users are encountering when submitting your form can be caused by several issues. Here are some common reasons and solutions to try:

    • Network problems: A weak or unstable internet connection can cause the server to disconnect, resulting in this error. Ensure users have a stable connection.
    • Inactivity: If users take too long to fill out the form, the server may disconnect them. Consider making your form shorter for better completion rates.
    • Caching issues: Sometimes an old cache of your form can cause submission errors. Clearing your form's cache can help resolve this. You can clear your form cache from your Jotform account settings.

    If these steps do not resolve the issue, please check if your form is using any payment integrations or other third-party widgets that might be causing the error, and try removing and re-adding them.

    For more details on clearing your form cache, you can refer to the Jotform guide on How to Clear Your Form Cache.

    Give it a try and let us know how it goes.

    Hi Ivan,

    I cloned and tested your form, and I ran into the same issue. Check out the screencast below to see my result:

    
Form Submission: Error 502 Request Failed Preventing Form Submissions
Image-1 After further checking and testing, I found the cause of the issue. I reviewed your subscription configuration and noticed that the subscription description shows [object Object], while in the Form Builder it displays Including VELOCE branded merchandise. This indicates that the subscription description is corrupted.

    To resolve this, I suggest manually updating the Subscription Description to match the correct value. Let me show you how:

    1. In Form Builder, on the right side part of the page, click on the Credit Card icon.
    2. Then, on the right side of the Product List field, click on the Stacked Coins icon.
    3. Now, navigate to your Subscription and click on the Pencil icon to access its settings.
    4. Finally, under the Description section, input the desired description and click on Save to apply the changes you've made.

Image-3Could you go ahead and submit a test entry through your form to check if the issue still occurs. If it does,, can you share a quick screen recording of what’s happening so we can try to replicate it on our end? You can upload it to Google Drive, Dropbox, or record with Loom and send us the link.

    Give it a try and let us know how it goes.
