How to disable SNI support for a particular domain in Plesk?
It is not possible to disable/enable SNI for a domain in Plesk. This feature has been already requested on UserVoice: Option to disable SNI for a domain in SSL Settings. The most popular suggestions are going to be implemented in the future Plesk versions.
As a workaround, SNI can be disabled/enabled from via IIS:
1. go to IIS Manager > Server > Sites > example.com > Bindings > select binding >
2. uncheck 'Require Server Name Indication' option.
Note: these changes will be overwritten by the next domain's settings update in Plesk.
