Project and energy disappeared

Some days ago my project and energy disappeared when connected on mobile data, while everything is ok when connected to wifi network. Server setting on the phone was instead of
Ping and changed the phone server setting to the web route me always to the wrong server (the one where neither project nor energy are accessible) independently from mobile or wifi network.
What can I do next?

Sorry, but this is exactly what I have already done! Now my server setting on the phone is but unfortunately this is not the server where my project and energy are stored!

What is your login email?
