Wiki won't sync - unexpected status: Forbidden

[TheManchineel]

Hello, I'm running DokuWiki 2020-07-29 "Hogfather" and XML-RPC is enabled, with remoteuser bearing my username. I've double-checked that the username and password (I use Auth-PDO for authentication) are correct.
The log:

I'm using Hogfather as well, without issue, however I didn't try if the Auth-PDO plugin would interfer with the XML-RPC mechanism ... that might be something to try on a debug install.
