RPC connectivity issue

[blockchain-app12]

I running the besu node setup in private chain. Totally 4 nodes.
1 node is master node and others are peer nodes.
Then none of the RPC method was not working while we trying to get response.
Kindly let me know the solution for the issue to resolve this.

Since you're trying to access a machine on AWS, I'm guessing the issue is in allowing that request in and out. By default, Besu accepts traffic from localhost/127.0.0.1 only. https://besu.hyperledger.org/en/stable/Reference/CLI/CLI-Syntax/#host-allowlist

• can you set host-allowlist=["*"] and retry
• if that works, then change ["*"] to the list of client IPs that you want to allow
• if you still get the same error, can you verify that executing the curl request from the same host can work ie accessing via localhost
