Forms not submitting - endless wait symbol :0

Some forms on my website are taking a very long time to submit, others are just not submitting at all, for example:

When you click submit, the ‘waiting’ symbol appears, but then nothing happens.

Any ideas?

I got a “server not found” error when attempting to access that URL:

This is a good opportunity for a support ticket:

These are not support forums, and you’ll likely get a better result from Gravity Forms support.

Thanks, that’s even stranger - I can access it from all devices, could you let me know if you are still experiencing this? I have opened a support ticket.
