Troubleshooting rpk "i/o timeout" issues when using Azure Private Link

  • Updated

 

Problem Statement

When trying to connect to Redpanda over an Azure Private endpoint using rpk a 
"i/o timeout"error is reported


Resolution 

Ensure the following : 

  • That  32092 is used for the port specified for the Private Link endpoint used in the rpk command (broker) e.g kafka-api-bootstrap-server-hostname:32092
  • The rpk/kafka commands are being attempted  from a VM that is running on the same Azure allowed subscription as configured in the setup following the Redpanda documentation 
  • The VM is on the same subnet/vnet as the Private  endpoint
  • If there is a Network Security Group attached either to the subnet or the VM network interface   make sure it allows access to connect to the Private endpoint  over 30292/tcp and also the range 32092-32094 

If you still encounter issues, follow the  Microsoft document for troubleshooting Private endpoint connectivity issues  https://learn.microsoft.com/en-us/azure/private-link/troubleshoot-private-endpoint-connectivity

If all the above checks pass and you still encounter problems when trying to connect , or you have further questions, please reach out to Redpanda Support.
