Switch to offline mode when server is unreachable

Hello,

Today I noticed that the application did not automatically switch to offline mode when my server was offline, even though I had enabled the automatic switch in the network settings. My Wi-Fi was on and I had an internet connection.

Ideally, the application should detect when the server stops responding to pings within a reasonable timeout period and then switch to offline mode. It should also revert to online mode if the server becomes responsive again after a set period, perhaps using a polling mechanism.

This functionality would have allowed me to view my downloaded playlist while connected to Wi-Fi, even with the server down, without having to manually switch to offline mode. Currently, the "Loading playlist" screen remains stuck in online mode in these situations.
