blockscout unable to get block information on initial execution

Question

I'm building a POA network in a local environment.

After completing the connection to eth-netstats, I connected blockscout and checked http://localhost:4000, and I couldn't get the information about the blocks that were previously created. What's the problem?

this is my docker-compose.yml file but, blockscout is not working
