(Royal TSX 3.2.1, Remote Desktop FreeRDP 3.2.4)
When an attempt to RDP to a host fails, regardless of the underlying cause, the overly vague error message is popped up: "The connection failed. (Error Code: CONNECTERROR)". Greater detail on the cause can be found by events in the log viewer, however this is tedious. I would prefer to have slightly more detailed error messages, so that I may more quickly respond to issues of hostname resolution or host reachability.
I've enumerated a handful of scenarios that result in the vague error message that I had mentioned. I've also included additional notes on what I might find in the log viewer, as well as a description of the desired behavior/error message.
Hostname Resolution Failure
Example: foo.bar.com cannot be resolved to an IP address
Ex: Attempting to RDP to a windows computer on TCP 12345
