So I have come to login to the SnapCenter GUI today and all my hosts are showing as "Plug-in incompatible" and I think this is because SnapCenter can't see it's plug-in repository. When I check the Software tab under Settings the plugins show as "Package not uploaded".
The installer files do exist in the package repository directory, in this case "E:\ProgramData\NetApp\SnapCenter\Package Repository".
I've restarted the server and the services and no change.
Any ideas how I can get SnapCenter to discover the plug-ins are actually still there?
Update: It seems the "Check for Updates" may have found a new version but not downloaded it causing the Software tab to be looking for version 220.127.116.118 but the file in the Package Repository is 18.104.22.1689.
Is there a location I can download the package installers on their own and drop the new version of the file in the directory, I think that might solve the problem.
