i have some problem with a test-net horizon that is not syncing. I'm using the quickstart docker image and i see core is fully synced (state: "Synced!").
On horizon i see that history.latest_ledger and core_latest_ledger: 552182 are in sync and on the latest values corresponding to the pub-testnet. On the log i see, that horizon is ingesting the newest ledgers.
But on horizon the history.elder_ledger is somehow on 180735. Of course i can't see any new transactions in the horizon db.
Can someone explain please, what those 2 values mean? history.latest_ledger and history.elder_ledger.
Also, how can i get horizon to sync everything? I tried all different ways from https://www.stellar.org/developers/software/known-issues.html but nothing helps.
Also tried CATCHUP_COMPLETE=true with no luck.
