The cluster failed to establish a connection #3265

If you use calico vxlan mode, you must use kubernetes api datasorce, but cannot connect to etcd directly. Otherwise, ippool cannot be discovered. After I modify, I still cannot create a connection [root@yonsuite-test-172-20-30-245 subctl]# subctl diagnose all ✓ Non-Globalnet deployment detected - checking that cluster CIDRs do not overlap ✓ Checking Submariner support for the CNI network plugin ✓ Checking that services have been exported properly Skipping inter-cluster firewall check as it requires two kubeconfigs. Please run "subctl diagnose firewall inter-cluster" command manually. subctl version: devel |

Hi @xuchuan-666 , From subctl gather I can only see cluster1 endpoint (cluster1-submariner-cable-cluster1-172-20-30-75 ) , can you check GW pod logs in cluster2 ? |
What happened:
all components of cluster1 and cluster2 are correct and logs are normal, and no errors are reported. However, the two clusters are not connected. For example, diagnose all of them by subctl and some of them are not ready, but I created them according to requirements
What you expected to happen:
The cluster can create connections
How to reproduce it (as minimally and precisely as possible):
