The correct version of OpenSSL for the NMC version was used:
NetWorker: NMC GST service starts then immediately shuts down after replacing cakey.pem
Причина
Encoding issue of the cakey.pem file.
The cakey.pem file was created using PowerShell. The default Out-File format is UTF-16 LE. The file is not read correctly during GSTD service start up, causing the failure.
Разрешение
When creating the cakey.pem file using PowerShell, enforce ASCII encoding.
Example:
Get-Content C:\tmp\server.key.pem, C:\tmp\server.crt.pem | Out-File C:\tmp\cakey.pem -Encoding ascii
