NEW sccm pex not deploy

[joreg328]

Hello
Recently I have been unable to install new computers in the organization through PEX even though there is a driver for the computer
And I can't install on old computers that have returned to installation, even though I removed the computer name from the system in both cases I get this message from the server log - I'd appreciate help!!!

you have to deploy your task sequence to Unknow computers collection. it says in the logs no advertisement found. there is also the possibility of duplicate computer name in SCCM.
