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 Plesk 360 (formerly known as My Plesk) 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.

    I have the same issue. Running Centos 7 with clean install of Plesk 17.5.3. However there is no apache2 folder or any apache2.

    @Ken, this article is for Debian based systems.

    Make sure that mod_ssl package is installed:

    # yum install mod_ssl

    If not, reinstall it and reconfigure apache:

    # yum reinstall mod_ssl -y

    # plesk repair web -y

    Let me know the result.
