WCO Base Station v1 ethernet connection issue to mesh node

WCO base station v1 does not connect to mesh system node via ethernet. Have been running ethernet for 3 years thru my Motorola gateway. Would like to move to new TP Link Deco XE75/AXE5400 (router mode) with ethernet. Prefer not to go WiFi and will stay with current gateway ethernet connection if necessary.

Any users with the same issue or other mesh network issues worth noting for future reference?

Disconnected the power supply and the ethernet cable; reconnected the ethernet cable first and then the power supply; the base station found the mesh network and reconnected successfully, Outdoor cams are back up and online without loss of any data.
