• The domain may be created in Plesk without hosting;

Cause

An unsuccessful attempt to create or remove subscription with the same name previously

Resolution

1. Log into Plesk.

2. Go to Domains and check if the domain example.com exists. If it does, remove it.

3. Connect to the server via RDP.

4. Go to IIS > Sites > example.com and remove the site.

5. Go to IIS > Application Pools > example.com(domain)(pool) and remove the application pool.

6. Create subscription example.com in Plesk again.
