Unable to connect Facebook Ads to HubSpot – OAuth loop despite full permissions

[rjelena]

Hi,

I’m trying to connect Facebook Ads to HubSpot (free account), but the OAuth authorization keeps failing.

I have full control over:

– Meta Business Portfolio

– Facebook Page

– Ad Account (owned by the same business, not shared)

– Pixel

When I click “Continue as [my name]” in the Meta permissions window, I’m redirected back and the connection fails with no error message.

I already removed HubSpot from Facebook Business Integrations, disconnected Ads in HubSpot, tried incognito browsers, and reconnected from scratch.

Ad Account ID: [ID]

Could a HubSpot moderator please reset the Facebook Ads OAuth connection or advise if there’s a known issue?
