bug
**Internal/External**
*External*
**Summary**
Unable to synchronize when se… tting up a new node
**Steps to reproduce**
1. Download the latest Cardano node build (I'm using version `1.27.0` and build `6413627`)
2. Download configs and genesis file (I'm using version `6426791`):
````
export LAST_BUILD=$(curl -s https://hydra.iohk.io/job/Cardano/cardano-node/cardano-deployment/latest-finished/download/1/index.html | grep -e "This item has moved" | sed -e 's/.*build\/\(.*\)\/download.*/\1/')
wget -q -O mainnet-config.json https://hydra.iohk.io/build/${LAST_BUILD}/download/1/mainnet-config.json
wget -q -O mainnet-byron-genesis.json https://hydra.iohk.io/build/${LAST_BUILD}/download/1/mainnet-byron-genesis.json
wget -q -O mainnet-shelley-genesis.json https://hydra.iohk.io/build/${LAST_BUILD}/download/1/mainnet-shelley-genesis.json
wget -q -O mainnet-topology.json https://hydra.iohk.io/build/${LAST_BUILD}/download/1/mainnet-topology.json
````
3. Create a cardano node with:
````
cardano-node run \
--config xxx/cnode/config/mainnet-config.json \
--topology xxx/cnode/config/mainnet-topology.json \
--database-path xxx/cnode/db/ \
--socket-path xxx/cnode/sockets/node.socket \
--port 3001
````
**Unexpected behavior**
The node is syncing properly until about block `4492800` (shelley era begin?) and starts to throw errors. I tried deleting the `ledger` and `volatile` folders in the database, but the errors still appear. Error log:

I replaced these files on both my block producer and relay’s cardano-my-node directory with the ones from the mainnet link there. Then restart the cardano service on both nodes.
