checkBlocksFullySynced: misc_store missing entries for best-synced, best_chain_tip or both

[MerlinB]

Having some trouble getting Nexa to run properly. debug.log is getting spammed with checkBlocksFullySynced: misc_store missing entries for best-synced, best_chain_tip or both and SocketConnectException. Ports should all be open. As far as I can see, nothing ever gets saved into the database.
If I enable debug logging the log looks like this:
