Not getting correct JSON from server. server OK?

[Saylrman64]

Hello,

I'm using the QOwnnote API on my Owncloud 10 server and their site indicated your app would work with their API.
So I've installed this app (from Google Play Store) and configured to point to my Owncloud server but I get the error: Not getting correct JSON from server. server OK?

My phone is Android 7 and I have the OwnCloud Client installed and working.

I cannot find anything on troubleshooting for the app that helps. Most everything is for the 1.x versions.

Any help is appreciated.
Thanks

If this is still current:
Try creating a folder named "Notes" in the topmost directory, which can be done in the MyOwnCloud app as well. After that everything should work. Here I use my employer's OwnCloud. There is no JSON, but upon creation of the Notes folder, the MyOwnNotes app synced all notes as ASCII (text) files in the Notes folder...
