WooCommerce Sync failing – server_error – There was a general server error. (500

Hi,

I installed and activated CRM today, as Jetpack kept asking me to

Apparently I still had some old data from 6 years ago when I previously had jetpack installed. I see that I still have transactions that were previously imported in 2017. New orders that are being placed are also syncing, but there’s a 6 year gap from when CRM was not installed.

So now I would like to sync the transactions up to now.

Commence WooSync.

WooCommerce Sync failing – server_error – There was a general server error. (500)

*sad face*

So something blocking it? My server not letting the thing happen?
It doesn’t seem to be linked to Cloudflare or other CDN/Caching setups. Cloudflare should automatically allow Jetpack, and I’ve turned all of those things off now.

Any ideas as to what I might be doing wrong?

Thanks,
