problem lies in

1、Upgrade to Mainnet - v1.10.32 latest sh -c “$(curl -sSfL https://release.solana.com/v1.10.32/install)” 2、After restarting and running for a while, when I use the interface to request port 8899, it has been stuck with no data

curl -s -X POST -H "Content-Type: application/json" -d '{"jsonrpc":"2.0","id":1, "method":"getEpochInfo"}' http://localhost:8899|jq

Is there any solution to my problem?
