Errors in log 0 ???

I'm seeing this quite frequently in the last few days:

[20-02-20 22:28:56.5000] Slim::Networking::SqueezeNetwork::Players::_player s_error (377) Unable to get players from SN: Couldn't resolve IP address for: www.mysqueezebox.com, retrying in 900 seconds
[20-02-20 23:14:03.2620] Slim::Networking::Async::connect (114) Failed to connect to www.mysqueezebox.com:443, because
Net::HTTP: connect: No route to host
[20-02-20 23:14:03.2654] Slim::Networking::SqueezeNetwork::Players::_player s_error (377) Unable to get players from SN: Connect timed out: No route to host, retrying in 900 seconds

Is this a network issue - flaky DNS ?
