On October 19, 2021, we have enabled single-sign-on for our Plesk Support Center to provide a seamless login/account experience. This implies that you’ll be able to use a single account across any of our web-facing properties.
If you had already registered your account at MyPlesk.com/Plesk360/Platform360 please use one for login. Otherwise please re-register it using the same email address as your existing Zendesk login (support account). It’s essential that you use the same email address on our support center to ensure that your tickets stay attached to the same account.

Unable to secure Plesk panel with Let's Encrypt: Invalid port in redirect target. Only ports 80 and 443 are supported, not 8443

    The resolution is not always applicable. I would prefer a workaround with a Nginx config file in /etc/nginx/conf.d/ which handles the redirect to 8443 but also handles LE ACME requests.
