Enable SNI for Primary Domain

My "primary domain" is receiving an odd 421 Misredirect Error. The full error reads: " The client needs a new connection for this request as the requested host name does not match the Server Name Indication (SNI) in use for this connection. " In WHM, under the Manage SSL Host section, the primary domain, it the "Is SNI Required?" field is marked "No". I imagine this pertains to my error in some way but if so, is there a way to mark it "Yes"? I've read the documentation here but I don't see a way to configure this section:

  Hello, cPanel has supported and enabled SNI since version 11.38 or newer as long as the server is running CentOS 6 or higher. Is the server currently running http2? rpm -qa |grep ea-apache24-mod_http2.x86_64

  Thanks @cPanelAaronH I was able to figure it out. It was an error within my CDN and unrelated to the server itself. Take care and stay safe, I really appreciate it!
