Error 404 While Submitting Forms Using Dynamic Data Linking

We are currently facing a critical issue while submitting forms to the server using the Kobo Collect app. Our study is a longitudinal cohort study, where we collect data from each participant at multiple time points. To facilitate this, we are using dynamic data linking to connect different forms.

However, whenever our team attempts to send data to the server, we encounter a 404 error, making it difficult to proceed with data collection. We have attached relevant screenshots of the error for your reference.

Thank you for your attention and support.
