Can’t connect to self-hosted Matomo

I can’t get the plugin to connect to my self-hosted Matomo. I’m following the instructions, I’ve got the auth token, it just doesn’t work.

error:
WP-Matomo 1.0.27 was not able to connect to Matomo using your configuration. Check the ?Connect to Matomo? section below.

test script result:
