Name Resolution Exception

[nirvdrum]

I'm running into a problem where this extension fails to perform name resolution when initializing, retries a few times (which also fail), and then gives up, moving to an unusable state. I'm running Raspberry Pi OS with wifi as my sole network interface. The mopidy service is configured to come up after network-online.target, so I'm not entirely sure why name resolution is failing. I suspect even though the interface is available, it hasn't finished configuring via DHCP.

All request types fail so I've only shown a couple in the following backtrace from the mopidy service log. If you need more, I can pull it together but I need to strip the token value out of them:

ERROR    [Thread-4] mopidy_ytmusic YTMusic failed to load auto playlists

During handling of the above exception, another exception occurred:

My solution for the time being is to manually restart the service. Everything works fine after that. Please let me know if you need any more info. My naive thought is that a back-off algorithm would help by progressively increasing the time between each retry attempt. Alternatively, a configuration for max number of retries ought to allow me to bump the threshold high enough that the requests eventually succeed.
