Unable to follow account

I've got an issue with one Wordpress site that runs the AP plugin, despite not having the same issue on three other Wordpress sites that run the plugin. I receive an error when trying to follow @ethicalrevolution@climatejustice.social (my personal mastodon account) from @theindiebeat@theindiebeat.fm (my Wordpress ActivityPub blog profile).

The climatejustice.social instance doesn't appear to have blocked theindiebeat.fm because I am able to see the @theindiebeat@theindiebeat.fm from my personal Mastodon account.

Any ideas why this may be? Here is the error:

Unable to follow account “@ethicalrevolution@climatejustice.social”. Please verify the account exists and try again.

Seems to be no general issue. I would assume it is a timeout issue! Will have a deeper look on monday.
