0x104 rd client error

I am using Apple MacBook Pro 15-inch Retina with native Apple Mac OS X Catalina 10.15.7 installed, Microsoft Remote Desktop client for Mac OS X version 10.4.1 (1825), and it was working fine even with earlier versions of Mac OS X and RDC client since March 2020, but once after September 2020 I am receiving error message when trying to connect to the same terminal server under Windows Server 2012 R2 Standard: «Unable to connect - We couldn’t connect to the remote PC because the license for this device isn’t valid. Contact your network administrator for assistance. Error code: 0x104.»

And it is even more strange that from the same Mac, using Microsoft Remote Desktop client for Mac OS X Beta - version 10.4.1 (1818) - I am connecting with no any problems. The key factors are: 'the license for this device isn’t valid', error code 0x104 and Microsoft Remote Desktop client for Mac OS X beta - version 10.4.1 (1818) works fine.

Seem that Microsoft Remote Desktop client for Mac OS X creates some folder or file with license information which should be removed to allow RDC to connect - as beta client works fine and I believe it is installed to another folder.

My solution: in folder '/Users/'user_name'/Library/containers' rename (or remove) two folders: 'com.microsoft.rdc.macos.qlx' и 'com.microsoft.rdc.macos'. After just re-install Microsoft Remote Desktop client for Mac OS X, error '0х104' disappears, and client becomes able to connect to remote server.

In all likelihood, there’s no network connection and no path available between the sites, or there’s a firewall or three that’s blocking that access. There’ll need to be either public static IP addresses for the target systems at the office and a path opened through the firewall, or private IP addresses and port-forwarding configured through the firewall, or a VPN configured and established between the remote client and the target network. Or IPv6 and a path through the firewall. There’ll probably want to be a public DNS name established for the target host, too.


Check with the local networking folks for assistance.
