Exchange Online PowerShell for Linux issue with Proxy

I have an issue using Connect-IPPSession cmdlet to connect to O365 Security & Compliance on Linux Powershell.

My server is behind a proxy, and I got this error message when running

*PS /root> $delegated_cred = New-Object System.Management.Automation.PSCredential ("$username", $secPassword)*

*PS /root> Connect-IPPSSession -Credential $delegated_cred*

**Connecting to remote server failed with the following error message : MI_RESULT_FAILED For more information, see the about_Remote_Troubleshooting Help** **topic**

The issue does not happen if running on a server with direct internet connectivity.

When we did packet capture to analyze when running the Connect-IPPSession cmdlet, the 3 URLs (,, were sent to Proxy correctly.

However, when it came to connecting to, it connected directly to the Microsoft server without going to proxy. That caused the connection issue. I wonder if this is a bug or any newer library to support?

Here are what I am using, also tried PS 7.2 and EXO 3.1, 3.0, 2.0.6 prerelease, same issue.
