Dubbo 3.2.11
### Steps to reproduce this issue
Use triple call provider api with istio sidecar injection, after about 1-2 hours, get RPC error, the log shows no provider problem.
By troubleshooting, we found the problem may be netty get the wrong connection status, the connection is health, but netty mark it as bad, so the RPC has been terminated.

Contributor guide
Research direction
Start by reproducing the Dubbo 3.2.11 Java SDK triple call with Istio sidecar injection and observe the failure after 1–2 hours. Inspect the Netty connection-status handling and logs; done means healthy connections remain usable and RPC calls no longer terminate with a no-provider error.
