VM network configuration Not found while the network still works
I have an app running on an Azure virtual machine, and today when I went into the portal to change the network access rule to access it via ssh I got this error from the screenshot. Namely, the network configuration page is "Not found". And I can't make any changes, it show as if no network interfaces are attached etc. But the main thing is the app works fine and I could connect to it via ssh until my ip changed, so the network is there, but the portal isn't showing it correctly I guess.
Also, the overview shows nothing:
Do you know what can cause this and how to fix it? Again, i have to emphasise, the app is available at the public ip address (which isn't displayed now on the portal.
