Patreon does not appear to be syncing on our instance

We’re on a hosted instance on discourse.group. We have the Patreon plug-in configured to update a group called Patrons, and anyone of any tier should be included in that group. Right now, despite over 1000 active patrons on Patreon, this group has only ~70 members, which seems like it’s far too small, especially considering that except for a few people given direct invites we’ve only supported people signing in with Patreon.

It has been two days since the sync has run according to the plug-ins panel in admin, contrary to documentation that suggests it should run ever y 6 hours, and that last run coincided with several people being dropped from this group, and a failure in the log (that appears to be a response from CloudFlare and not api.patreon.com itself.) We see similar failures at roughly two week intervals.

Clicking the “Update Patreon Data & Sync Groups” button in the plugin’s admin panel appears to do nothing (we have verbose logging enabled for the plug-in, and nothing is logged.)

I do not personally have admin access to the Patreon account we’re tied to, but if I use the creator token set up for the plugin against the API endpoints (with curl) it does work and I am able to get valid responses, page through pledges, etc. There was an earlier thread that suggested that the request limits for that instance needed to be increased; I did that on our instance but it appears to have had no effect.

I’ve looked at a few relevant threads:

But from what I can see it just looks like synchronization isn’t happening either manually or on a schedule, or at least not on the 4x daily schedule the documentation implies, and as we’re not self-hosting I think I’m at the limit of what I can inspect myself.
