Keep getting Error reloading accounts: FetchError: request to rpc failed, reason: socket hang up, for all subsequent refreshAccounts method call

The code successfully fetches the mango accounts in the initial refreshAccounts call, but for all subsequent calls it gives Error reloading accounts: FetchError: request to rpc failed, reason: socket hang up.

Hi @anishsamant, this sounds like an issue with your RPC provider. Please check you are not being rate limited or similar

[samlaf]

Were you using the solana endpoint (https://api.devnet.solana.com) instead of mango endpoint (https://mango.rpcpool.com/946ef7337da3f5b8d3e4a34e7f88) by any chance @anishsamant ?

I'm observing similar behavior when using the solana public endpoint. First getting

Error: Error reloading accounts: FetchError: request to https://api.mainnet-beta.solana.com/ failed, reason: socket hang up

and when I retry I get
