Reset settings ins content in Joplin Server with Docker

I can only guess that it is a typo when you set the new password that is causing the problem. Try a reset again.

Joplin does not provide a Joplin Server image for ARM however others do. This post gives links to Docker Hub for images provided by florider89 and etechonomy and they are normally updated to the latest version very quickly after the latest official version is released.
