This is most likely due to a circuit being recycled on the server after some time.
Then when mobile browser is resuming after a long time it shows the "connection lost, retrying..." dialog for 3 seconds (default), then tries to reconnect, but this attempt is immediately rejected because server-side circuit was already disposed and results in Could not reconnect to the server. Reload the page to restore functionality message.

See #32113
