External formular no longer pushing data

Hello, we have noticed a blocking of contact submissions on the hubspot external form below since 17/02 at 2pm:

External form name: .flex, .h-full, .flex-col, .justify-between, .md:pr-0
Form link on webapp: Nostrum Care?

No more contacts have been sent via this form since 17/02/25 at 2pm, even though the hubspot tracking code is fully functional on GTM. The code base has not been modified for weeks.

Hubspot support has also noticed the problem despite cookie acceptation. We have a cookie acceptance rate of 76% according to Axeptio.

For your information, here’s the system we’ve set up:
- If the visitor accepts the cookies and fills in the form, then the data is uploaded to hubspot via the hubspot external form .flex, .h-full, .flex-col, .justify-between, .md:pr-0 and the values of the utm fields are also uploaded.
Using this method, we can have the following fields: Source of original traffic, Information on source of original traffic 1, Information on source of original traffic 2.
- If the visitor refuses cookies and fills in the form, the data is sent back to hubspot via N8N.

Something on the Hubspot side seems to be blocking .flex, .h-full, .flex-col, .justify-between, .md:pr-0 form submissions (in case of cookie acceptance) as well as contact submissions via N8N (in case of cookie refusal).

Hubspot support asked us to make a ticket here to solve the problem. Our dev Mathias (who made the base code) stands ready to discuss with to solve this problem.

Thank you for your help.

Hi, @mtrennert Thank you for providing the details about your issue. To be clear, the HubSpot community is a place for peer-to-peer support, and our community members may not be able to help troubleshoot a complex custom integration that involves:

  • a dual submission system
  • custom UTM handling

Some troubleshooting steps your developer can take to give our community more information are:

  • review the browser console for any JavaScript errors when form submissions occur
  • verify the HubSpot tracking code is firing correctly using the HubSpot debug tool (add ‘?hsDebug=true’ to your URL)
  • test a simple HubSpot native form on the same page to isolate if the issue is specific to your custom implementation

Please share any error messages you see in the browser console during submission attempts.

This will help the community better understand and potentially assist with your issue, though you will likely need to work with developer resources for a complete resolution.​​​​​​​​​​​​​​​​

Best,

Jaycee
