The following versions are potentially impacted:
This will also affect the the versions mentioned in the KB if you are renewing third party SSL certificates with the AWCM reinstallation method.
Because the cab-files in the installation media seems to be signed with the same certificate.
I was concerned about that expired certificate using the full installer as well. I submitted a TICKET #21206638403. We first tried to just uninstall the Device Services (DS) using the full installer and modifying the existing installation per their documentation and that failed. We ended up using the Programs & Features control panel to completely uninstall Workspace One UEM from the DS server. I suppose we could also have used the newer Apps & features Setting to do the uninstall too. When not installed at all the installation went through completely without error and the newer SSL certificate was then used so AWCM was working again. We also applied the same patch upgrade to match the other servers at the time (.19). We had to disable the Windows Defender firewall to allow domain network connections to port 2001 as well.
Thanks for the explanation. That worked for me as well:
1] Snapshot VM.
2] Completely uninstall Workspace One (via Programs/Features)
3] Reinstall using 20.11.05 Full Installer.
4] Include custom certificates when prompted.
5] Re-patch as needed.
Harrowing, but it worked. Now AWCM is once again running with the proper certificate. 👍
