Hi @ghaleez ,
Couchbase 6.6.0 does not support Moxi (neither client-side nor server-side). My understanding is that the Moxi port remains configurable only to enable migration away from Moxi.
There are still some misleading references to Moxi in the documentation like the page you cited; this issue is being tracked as DOC-5795 where there’s currently an active discussion.
Thanks,
David
