Adding linkerd proxy creates too many connection errors

Injected linkerd proxy in mysqlrouter and the services are able to connect to db through proxy and mTLS is in place. But after few minutes, the services are getting too many connection errors from mysql. Without injecting the proxy, there is no connection issue. The annotations added are as below:

      linkerd.io/inject: enabled
      config.linkerd.io/skip-outbound-ports: "8192"
      config.linkerd.io/proxy-outbound-discovery-cache-unused-timeout: "0.2"
      config.linkerd.io/proxy-inbound-discovery-cache-unused-timeout: "0.2"

Are there any additional configs to be added to fix this error?
