3rd Party: Hubspot connections are failing with Reconnect error "We were denied access to HubSpot. Please check the accuracy of your credentials"

We have confirmed that instance rates have returned to normal and connectors are now syncing successfully.

Incident Summary
Description:
HubSpot connectors were failing with a reconnect error: "We were denied access to HubSpot. Please check the accuracy of your credentials."

Timeline:
Start: 20:30 UTC
Resolution: 08:30 UTC

Cause:
A change introduced on HubSpot’s side caused unexpected 403 errors from the /property/{crm_object} endpoint.

Resolution:
HubSpot identified the issue and deployed a fix on their end, restoring normal functionality.

We are continuing to monitor for any further issues.

A fix has been implemented and we are monitoring the results.

We have merged a hotfix to skip the affected endpoints. We will monitor the connections once the hotfix is deployed

We are currently seeing failures for HubSpot connectors due to changes in source API requirements for certain Engagement CRM objects (Calls, Notes, Meetings, Tasks). Connections are returning 403 errors when accessing affected endpoints.

Our team has contacted the HubSpot team and is working on a temporary fix, skipping these objects until we receive further clarification. We will provide updates as we learn more.

The issue has been identified and we are working to resolve it.
