Hi @SLinHennef, when you sign into your account on the app, please ensure that you enter your sync server URL in the Advanced options menu:

Thanks @effieeee - but this is perfectly clear. I know how to login. But as far as I understood the documentation (https://github.com/standardnotes/app) one should be able to define a standardsync-server within the selfhosted web app.

But the options tested so far with the docker-compose did not change the standard-syncserver for my selfhosted webapp.
