I know Umbraco 8 is out of support, I am seeing this on our last Umbraco 8 site we look after.
I assume the upgrade server for Umbraco 8 is down ??
Found this old pose what made me make that assumption No MediaTypeFormatter is available to read an object of type 'UpgradeResult' from content with media type 'text/html'. · Issue #10079 · umbraco/Umbraco-CMS · GitHub

Heya @darrenhunterEmerald!
I was convinced that the upgrade checker would just fail silently so that endpoint has been returning a 410 since we turned Our Umbraco off last week. But clearly.. it did not do the right thing!
I’ve updated it now so it sends an empty response back so you don’t see this error any more. Can you give it a try and report back?
Thanks!
That fixed it
Thank you.
