I have noticed that after upgrading to 2023.1 and next to 2023.2, I still have old SHA1 certificate for WPM Playback. This could be a potential security issue.
Below release notes for WPM 2023.1 include new certificate:
"WPM SSL Certificate is now signed using SHA256 encryption algorithm or higher."
I have manually removed it from Certificate Authority and ran Configuration Wizard. This resolved my problem and now I have SHA512 certificate:
However, this should be replace during the upgrade process. I hope this helps you and SolarWinds will correct the installer
Take care, Marcin.
Update: As per discussion in comments, as an alternative solution, you could delete the certificate and restart the machine. New certificate will be created without running Configuration Wizard.
