2-5 - Filter Provider Failed

Possible Reason

  • Dubbo will finally select a provider from the provider list to initiate a call during load balancing. During the selection process, the provider list changes, and read-write conflicts occur, resulting in screening exceptions.
  • When the Dubbo retry mechanism fails to call the provider, it will re-screen another provider to initiate the call, and an exception occurs during the re-screening process.

Troubleshooting and resolution steps

  1. Check the registry provider list and the availability of the corresponding provider.
  2. Raise an issue in the community, provide environmental site information and reproduction steps.
