Hi @baran,
Does your primary machine and tablet device connected on the same local area network?
Do you maybe have VPN (Virtual Private Network) active?
Do you have any third party firewall software that might probably blocking the spacedesk connection?
If yes, please make sure to add spacedesk or “c:\Windows\system32\spacedeskService.exe” on your exception list to allow incoming/outgoing connection.
For assistance, please also check Troubleshooting – Network Connection chapter in our user manual.
