Hi, I updated my OC200 controller earlier this week and after that, I saw a warning message advising that the inbuilt RADIUS feature will be deprecated/removed completely in 5.15, eg: Why is Built-in

TP-LINK is removing OpenAPI and RADIUS from the OC200 controller in v5.15. This is NOT OK - it's really very poor corporate behaviour, and highly damaging to customer's trust in your product offering.

Trying to access the Open API against my hardware OC200 controller, but always get a Client/Secret invalid error. Following instructions here https://use1-omada-northbound.tplinkcloud.com/doc.html#/ho

NOTE: this is for the RE455 not the RE450. RE455 was not available for selection in the Model list pulldown Basical Issue - No Internet from devices connected to the extender. Configuration Successful
