I’m thinking the issue is that the LogClient in 2020 R3 MIP SDK is unable to communicate with the Log Servers older than 2018 R3.
We implemented a new Log Server and made breaking changes requiring recompile to support the newer Log Server and I’m assuming the reverse is also true - the 2018 R3 and later SDK’s are unable to communicate with the old log server component.
Restructuring MilestonePSTools to enable the user to select the SDK version they want to use is probably the only way to make Get-Log work in this situation and that is a fairly large undertaking that I am not prepared to do.
If it’s not feasible to upgrade to at least 2018 R3, I’m afraid the only option may be to write this yourself either in C# or PowerShell using the 2018 R1 MIP SDK binaries. Here’s how the Get-Log cmdlet is written in C# for reference:
using System;
using System.Collections;
using System.Management.Automation;
using VideoOS.Platform.Log;
namespace MilestonePSTools.Commands
