New Pleskian
On Windows, I have a client that uses Worldpay for their eCommerce. Worldpay do not support SNI

Following previous advice I have created separate IP address for the production and test website not shared with any other domain and then using IIS switched off SNI

Worked fine last year and this year till now.

Now I find that Plesk is switching SNI back on when obtaining a new LetsEncrypt certificate. Hence I get unannounced instant and permanent failure of eCommerce processes due to Worldpay unable to access our server.

How do I stop Plesk messing with SNI settings
