Windows Inventory checkin Received an unexpected EOF or 0 bytes

I began having an issue with my jamf enrollment for Windows around 07/07/16. Possibly around the time I upgraded from 9.91 to 9.92. I knew something was wrong but realized this morning that no Windows Computers were even checking in. I ran the jamf.exe manually with parameters and here is the error:

PS S:> C:WindowsTempjamf.exe recon -overrideJSS https://jss.psd401.net:8443 -username imaging -password imaging -allowInvalidCertificate -ssl true

Running system Recon... Overriding JSS Url. Url to be used -> https://jss.psd401.net:8443 Overriding AllowInvalidCertificate -> True Retrieving Inventory Preferences from https://jss.psd401.net:8443/... There was an unexpected error executing the command 'jamf.Commands.CommandRecon'!

I've tried using the newest version of Recon.exe with the same result. Note: My JSS is not behind a load balancer. I've had successful Windows inventory since early June.
Has anybody seen this error?

The error was caused by disabling TLSv1.
