After uploading and selecting of the new SSL/TLS certificate via Plesk UI an old certificate is still shown in browser for the website noted in Plesk https://www.example.com.
In Plesk settings and in IIS new certificate is shown as assigned and valid.
Cause is unclear. Probably an old certificate file is cached in IIS.
2. Navigate to tab Home > Domains > example.com > Hosting settings.
