I had this one time and seems happen only if you change that setting in-flight. May be some what with the cache will then not work fine or it needs a long time to renew the data, but it is not related to “connection lost”.
Recommendation: do in special the network settings ( which affects the cache etc, ) before you start your flight. This in in general valid, because we have also topics like that ( Flickering parked cars when increasing road vehicles graphics setting ) , which happen only if you change settings in-flight.
