I'm running into an issue when attempting to register a machine to any given environment of ours. The error is as follows:
"An error occurred while registering your machine, please check your network connection settings or contact your administrator."

I have a matching machine that I'm attempting to join in a machine group together and this other machine does not run into any issues (same specs/setup).
After the failed registration, the machine will show up in Power Automate as offline despite it being power up and online.
Steps Completed:
-Reinstalled same version of PAD
-Removed all local PAD files and installed latest version as admin from PA site
-Tried registering to multiple environments that other machines have no issues with
-Used multiple accounts that all have the requisite access and work on other machines
-Confirmed .NET Framework version (4.8)
-Ensured the following reg key exists and has proper permissions (Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Power Automate Desktop)
-Did not find any conflicts with the port number for PAD, but this is not my expertise
Any help would be appreciated, thanks.
