Multiple async connections in nodejs gRPC

[0xvoid]

when sending one request the gRPC server from a rest api (that acts as a gRPC client), the server returns it successfully, but when sending multiple requests at the same time the server returns the following error:

FetchError: request to "api/pay" failed, reason: getaddrinfo EAI_AGAIN "api" at ClientRequest.<anonymous> (file://node_modules/node-fetch/src/index.js:108:11) at ClientRequest.emit (node:events:539:35) at TLSSocket.socketErrorListener (node:_http_client:454:9) at TLSSocket.emit (node:events:527:28) at emitErrorNT (node:internal/streams/destroy:157:8) at emitErrorCloseNT (node:internal/streams/destroy:122:3) at processTicksAndRejections (node:internal/process/task_queues:83:21) { type: 'system', errno: 'EAI_AGAIN', code: 'EAI_AGAIN', erroredSysCall: 'getaddrinfo' }
How can I solve this and make multiple calls to server without failing?

This is a DNS error that is occurring when making an HTTP request. gRPC is not involved here.
