DR5 Preparation

I am preparing for the upcoming DR5 and when I execute the following command, it is failing.

Can someone help please?


 curl -X POST -H 'Content-Type: application/json' -d '{"jsonrpc":"2.0","id":1, "method":"getTransactionCount"}' http://testnet.solana.com:8899


curl: (7) Failed to connect to testnet.solana.com port 8899: Connection refused

Hi that looks like the right command. The response indicates a connection issue, most likely the node was restarting. Does the error still occur for you?
