ST is running well on my Android 9.0 smartphone. I can open the web interface within the Synthing app without any problem.
If I try to open 127.0.0.1:8384 locally via the Chrome browser, a login dialog appears, that asks for credentials to access the page. I have not set up any username / password. I even can´t find any settings for that in the Android client.
Why is ST asking for login credentials?
