Unable to add sub/addon domains to any of our servers

Since the 86.0.8 we're unable to add sub/addon domains to any of our servers. getting the error message that looks like this (for both add/subdomains): (XID rkqxg8) Error ID 28bfff6d99280 I checked DNS zone and removed the records and tried again but it still did it. I also checked the tweak setting in WHM and the options look correct. Only recent change I'm aware of is that we're on cpanel 86.0.8 as of a few day ago. This is happening for all our customers across ~40 of hour hosting servers Anyone else seeing this or just me?
