Speaker Companion - Network or server error when adding

Using the new mobile app on a Pixel 3 XL

Trying to add ‘speaker companion’ to get my sonos speakers tell me when someone’s at my door (ring doorbell)

But every time i try to add this i get the error above.

Anyone have a solution?

BTW: I tried setting a IFTTT-thing for this but id rather use smartthings.
