IBM Watson NLU is not working with v5.5.1.53573 (Stable)

Hi every body, the connection to IBM Watson NLU, suddenly stop working… We review everything in both sides, Bright Pattern Contact Center Software and IBM Watson, I saw that the URL changed in IBM Watson, I already change the URL in BP but until now we can’t make it work. Does anyone know what is the correct url?

Looks like there was some kind of maintenance IBM Cloud Status
If you changed URL and it worked, that must be it
