Code signing warning (building for iOS on windows with remote compile on mac)

Untill recently I was able to build for iOS with a blueprint based project without any trouble (other than the usual certs and provisioning openssl rubbish)
But with 4.19 default projects with nothing done to them are wanting a mac and remote server to compile.

SO… I got a mac
Set up my certificates, permissions etc
Copied them to my PC
Generated the SSH key (no errors)
Then ran into the wall of red errors trying to build.

Followed EVERY guide to sort out why it does not work
Made allot of headway with some help from great posters step by step instructions on where to move the remotetoolchainprivate.key to etc and what permissions to set.

The FINAL wall I have is the build fails at code signing

LogPlayLevel: The following build commands failed:
LogPlayLevel: Check dependencies
LogPlayLevel: (1 failure)
LogPlayLevel: Execute took 00:00:01.9707549
LogPlayLevel: IPP ERROR: RPCCommand MakeApp failed with return code Error_RemoteCertificatesNotFound
Can anyone help ?
2 weeks beating my head over this one and I cant solve it.

Seems like your mac needs the provision profiles on it. Try downloading them from you apple dev account and installing them into your Macs Keychain.
