Below is the list of errors you may face when configuring a farm in SharePoint Manager Plus.
Possible reason
CredSSP authentication is not enabled on the client or server, causing the authentication request to get rejected.
Solution
Enable the CredSSP setting on both the client and server:
Possible reason

Restart-Service WinRM
If the error persists, you can try the following:
Get-Item wsman:\localhost\shell\MaxMemoryPerShellMB (Run this to check the current PowerShell memory size)
Set-Item wsman:\localhost\shell\MaxMemoryPerShellMB -Value 1024 -Force (Run this only if the memory is less than 1,024MB)
Restart-Service WinRM
Get-Item wsman:\localhost\shell\MaxShellsPerUser (Run this to check the maximum concurrent shells allowed per user)
Set-Item wsman:\localhost\shell\MaxShellsPerUser -Value 30 -Force (Run this only if the count is less than 30)

Solutions
Add-PSSnapin Microsoft.SharePoint.PowerShell
Get-SPDatabase | Add-SPShellAdmin DOMAIN\UserName [Replace DOMAIN\UserName with the actual user account]
Alternatively, you can do this by opening SQL Server Management Studio and assigning the DBCREATOR, SECURITYADMIN, and SYSADMIN server roles to the user. Also, ensure that the user has the DBOWNER privilege over all the SharePoint databases.

Possible reason
The installed PowerShell version is outdated and does not meet the minimum requirement for SharePoint Manager Plus.
Solution
SharePoint Manager Plus requires PowerShell version 2 and above to work. Upgrade to at least PowerShell version 2.
Possible reason
You may encounter these errors when attempting to connect using Remote Desktop Connection or when establishing a remote PowerShell connection. SharePoint Manager Plus uses CredSSP authentication to connect to SharePoint Server. A remote code execution vulnerability exists in the CredSSP protocol; this vulnerability (CVE-2018-0886) was addressed by a Microsoft security update. Both the client and the server need to be updated to resolve this.
Solution
Install the Microsoft security update on both the client and the SharePoint server.
Possible reason
This issue arises because the current .NET Runtime version is not compatible with Microsoft SharePoint's requirements. The default PowerShell version on most modern systems might be incompatible, thus causing the error.
Solution
Perform the following steps to create a custom PowerShell session configuration. The command below registers a PowerShell 2.0 session, ensuring SharePoint cmdlets run in a environment compatible with older .NET versions:
These steps will configure SharePoint Manager Plus to use the newly created session (ps2) for executing PowerShell commands, ensuring compatibility with Microsoft SharePoint.
