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.

    Hi

    Client installed directly through RDP:
    1. node-v12.18.0-x64.msi
    2. iisnode-express-v0.2.21-x86.msi

    Plesk panel application pool crashed and all other websites application pool also crashed.

    Corrected by below steps and also installed Node.js using Plesk.

    "C:\Program Files\iisnode" Deny permission for users psaadm_users,psaadm and psacln, changed to "read and execute".
    "C:\Program Files (x86)\iisnode" Only read permission were found changed to Read and execute.

    Note: permission changes from RDP not from DiskSecurity.xml though had entered same content mentioned in this KB.

    Just want to know how this can be corrected as I have run Plesk reconfigurator for all possible option available.

    how to add both location with correct permission.
