[Bug]: v0.27.4 Android App will not sign into Affine v0.27.4 self-hosted server

What happened?

Seemingly the same issue as reported for previous versions. Works fine using web client, Linux App. Fails with "Unable to sign in" message and "Network error" below the Server URL entry box. I have a simple Docker Engine setup without reverse proxy. I only need to be able to connect on my home LAN. I expected to be able to connect without any problems using the Android app.
