Hello,
since a few days I get the error message "CONNECTION_ERROR" when I call the method connectWithUserName().
Unfortunately I can't find any explanation what exactly the error message means, how it is caused and how to fix it.
Before that, I never had a problem with the connection.
I hope you can help me.
Edit:
I forgot to mention that I get the same error message via the dashboard when I try to connect a user there.
