Why do I receive another log-in request after logging in?

Q Why do I receive another log-in request after logging in? A We are currently developing a new login procedure. The aim is to get uniform mbNET login masks. Depending on the versions used for the mbNET firmware and the mbEDGE version, it can happen that you have to enter the login information twice: first in an mbNET mask and then directly in the Node-RED. If all components are up-to-date, this is no longer necessary.
