looks like a network connection issue.
Please make sure that both primary and secondary machine are connected on the same local area network.
If you have a third party firewall software, please make sure that spacedesk or C:\Windows\system32\spacedeskService.exe is included in the exception list for incoming and outgoing connection.
For more details, please check Troubleshooting -> Network Connection chapter in spacedesk user manual.
