I tried to deploy Dagster to our company’s host, and im getting this error when trying to open the workspace UI:
Copy code
dagster.serdes.ipc.DagsterIPCProtocolError: Timeout: read stream has not received any data in 15 seconds
it could be possibly caused by how long the deployment process takes which exceeds the timeout defined. The error was raised from
wait_for_grpc_server
, however, I did explicitly add below config to dagster.yaml, why it still tried to start a gRPC server?
Copy code
opt_in:
  local_servers: false
stacktrace:
