TMS on register Roomkit plus error

[Breeze]

Hi guys 

I use TMS and I'd upgrade it ver.15 -> 15.6.1

but still can't register Roomkit plus on TMS

when I try to register, TMS will show me this error message

"Index (zero based) must be greater than or equal to zero and less than the size of the argument list."

how can i fix it? plz help me

Thanks

Have you tried purging that system completely from TMS, then re-adding it?

If it continues to fail, then I'd suggest you try factory resetting the RoomKit, then adding it to TMS again, then reconfiguring it.  There may be some setting that is configured incorrectly on the endpoint causing TMS to throw the error.
