MailChimp Integration times out

I'm currently trying integrate MailChimp with Jotform and it keeps hanging at this phase (screenshot attached)

I searched the forums and saw someone suggest recreating the list at MailChimp and re-integrate, which I did, and still no luck with moving past this stage of the process.

Any clues as to why this is stalling out?

I've just tested the integration and worked ok on my side.

Let us know if the issue persists.
