Greetings,

On our website, we use the Forms API V3 no auth submission endpoint to submit forms. This works perfectly on desktop, but not on mobile (both Android and iOS). Using the Firefox Mobile DevTools extension, I can see that there is a general NetworkError, and that the status code is 0. Other requests work fine, so it is not a device or config error.

Is there a reason why this happens? Should I somehow allow mobile browsers to submit my form? Without any clear logs, I’m a bit stuck.

Hey, @TopHat 👋 I know I’m preaching to the choir here, but without more details, it’s hard for our community members to troubleshoot this with you. Do you have a link to the form? Or a page where there is a form we can test with or examine?

Thanks! – Jaycee

Thanks for your reply!

As I was mostly asking if there is a general form configuration or something like that I was missing, the actual form/code didn’t seem relevant yet. The form that’s currently causing the issue can be found [here.](https://www.vanroeyvastgoed.be/aanbod/sint-lenaarts-houthof#FORMULIER)

The original code was based on HubSpot’s Webflow plugin, which lacked some functionality. It has slowly been expanded upon, which explains some of the messier parts of the code. Most of it’s not relevant, though, since it’s just used for conditional fields, and things like that.

Like I said, the form works perfectly on desktop. Apart from that, I’m not sure if there are more relevant details I could share.

Update: since today, submitting forms works again on Chromium browsers on Android (Chrome and Vanadium). Firefox still exhibits the same behaviour as before. I have not yet made any changes to my code.

I have also tried disabling uBlock Origin, but this didn’t change anything.
