Remote Follow Fails

When trying to remote follow a user and filling in the remote follow form, my instance returns an error page

The url used is along the lines of:

<my-instance>/ostatus_subscribe?acct=https://<remote-instance>/users/<remote-user>

(where <> encapsulated word are replaced with real world values).

I've googled around and this appeared to be an issue years ago that was apparently fixed. I still have this problem wiht a brand new install from stable sources on 9th November 2022.

Is there anything I need to do in the configuration to fix this or has the 'bug' reappeared.

My instance is behind nginx with ssl

Found this in the log
