Hello, sir can you please share your network diagram ? one layer 2 switch (which is in stacking) to another layer 2 switch what is the port configuration ? in which L2 switch you have default vlan 1 only ? the one which is in stacking or the one which is after stacking ? appreciate if you can share the configuration of all devices to diagnose further.

Thank you,
