   ok, I have the same problem……
   
   my apisix `config.yaml`
   ```yaml
   apisix:
     admin_key:
       - name: "admin"
         key: edd1c9f034335f136f87ad84b625c8f1
         role: admin
     ssl:
       ssl_trusted_certificate: /usr/local/apisix/t/certs/mtls_ca.crt
   etcd:
     host:
       - "https://admin.apisix.dev:22379"
     prefix: "/apisix"
     tls:
       cert: /usr/local/apisix/t/certs/mtls_client.crt
       key: /usr/local/apisix/t/certs/mtls_client.key
   ```
   
   my etcd cluster is same as https://github.com/apache/apisix/blob/a2d80b73ed1d61a9f3e02bf2ddd5c4f2ffc4ddac/.github/workflows/build.yml#L140-L153
   
   I executed
   ```shell
   echo "127.0.0.1 admin.apisix.dev" | sudo tee -a /etc/hosts
   ```
   to set local domain
   
   and then, I use curl to verify that it is a problem with etcd 
   
   ```shell
   $ curl --cert /usr/local/apisix/t/certs/mtls_client.crt --key /usr/local/apisix/t/certs/mtls_client.key --cacert /usr/local/apisix/t/certs/mtls_ca.crt https://admin.apisix.dev:22379/version
   {"etcdserver":"3.4.13","etcdcluster":"3.4.0"}#        
   ```
   tt doesn't look like.
   
   here is my error.log
   
   ```
