Contact form submissions failing on slower connections, timeout or validation issue?

[LCarson2]

Hi everyone,

I’m troubleshooting a HubSpot form that sometimes fails to submit when users are on slower or unstable connections. The page just hangs or throws a vague error, which makes it hard to tell whether it’s a validation problem, a script timeout, or something related to network speed.

While testing this, I was comparing behavior across different internet packages, and it seems the issue shows up more often when bandwidth or latency isn’t great.

Has anyone here dealt with form reliability issues like this on HubSpot? Do you usually look first at script loading, timeout settings, or client-side validation when connections aren’t ideal?
