Hi @ced-edem,
Please check the Troubleshooting -> Network Connection chapter in the user manual https://forum.spacedesk.netuser-manual/.
If the troubleshooting steps did not help, please open the spacedesk Driver Console app on your primary machine, then click Diagnostics -> Save All Information.
PS: Saving all information will take a few seconds, then please send us the whole folder which contains all the diagnostic logs collected.
Please right-click the folder -> Send to -> Compressed (zipped) folder, then attach the *.zip file in your next reply.
