Yes, it did solve the issue.
But just wondering, why we need to restart the sntp. Can't we have an API which is just to sync time?

No, lwip sntp not reproduce a public API to send sntp request. As you saw, it is static and need need maintain some timeout function and state, so stopping sntp module and re-starting it is a easy way to send sntp request.

Is there a way to find out why the SNTP 'failed' in the first place?
I've tried just restarting until the current year is reported, but that doesn't seem to get me anywhere and just loop indefinitely.
