I found the answer on my own. It was due to the name of the entitlement being different between profiles generated on the portal and those generated in xcode. For example, to sign for development (with a development profile), the entitlement is packet-tunnel-provider, while it is packet-tunnel-provider-systemextension in the profile that is generated in the developer portal.

Also getting this (installing into Parallels as well) - interested in any solution.

Actually - there is another thread on it over at https://developer.apple.com/forums/thread/649774

There are two separate xcode downloads currently - one labelled "Xcode 12 beta" and one labelled "Xcode 12 for macOS Universal Apps beta". Make sure you grabbed the second one.

We are currently able to notarize apps signed with Company A’s certificate using Company B’s developer account. Is that changing?

Thank you! This is excellent information and gives me a great place to start.

I’m getting occasional WindowServer crashes - perhaps that is what is taking you back to the login prompt?

Thank you for the guidance!

I am seeing a crash in the WindowServer process. I can get it to happen every time when I click on the menubar (which is empty for me...i.e. no clock or any other icons). I have logged it as a feedback issue (FB7760353). If anyone is having problems where they keep getting thrown back to the login screen, you may want to check in /Library/Logs/DiagnosticReports and see if you have any WindowServer crashes.

@granada29 - I don't think it's an artifact of VirtualBox, because I'm seeing it in Parallels as well. It might be an artifact of virtualization, however.

@meaton - for that workaround you mention, is there a way to specify a wildcard for the port (instead of port 443)?

I can verify that upgrading to 11.1 beta 2 addresses this same issue I had as well.

I am seeing this starting this evening - did something happen again?

This is on a build server that has worked for years - nothing has changed on it or on its network. I sign (as a part of my build) 5 different binaries. A different one fails each time. I was able to take a PCAP from that machine during its build process - and it shows three successful time stamping as and a fourth request (with no corresponding response).

Also - for completeness of what I'm doing, I'm notarizing from command line using: xcrun altool -u "${APPLE_USERNAME}" \p "${ALTOOL_PASSWORD:-"@keychain:${APPSTORE_KEYSTORE_ITEM}"}" \ --asc-provider "${APPSTORE_ASC_PROVIDER}" \-notarize-app --transport DAV \ --primary-bundle-id "${APPSTORE_BUNDLE_ID}" \f "${PATH_TO_FILE}"
