Windows signing service 500 errors

Summary

The signing service has been returning error 500 today, it worked yesterday and I don't think we have any changes to the input

Steps to reproduce

curl -f --silent --show-error -o ../../org.eclipse.cdt.core.win32.x86_64/os/win32/x86_64/starter.exe -F file=@/tmp/production-TTyUQ5RcSJ/starter.exe https://cbi.eclipse.org/authenticode/sign

Where the input starter.exe is here in Eclipse CDT github

What is the current bug behavior?

00:05:25.445  [INFO]      [exec] curl: (22) The requested URL returned error: 500 

(extracted from https://ci.eclipse.org/cdt/job/cdt/job/main/416/console)

What is the expected correct behavior?

curl should silently and successfully complete, see previous build (https://ci.eclipse.org/cdt/job/cdt/job/main/415/consoleFull) for an example (search for [INFO] [exec] + curl -f --silent --show-error -o ../../org.eclipse.cdt.core.win32.x86_64/os/win32/x86_64/starter.exe to see the line

Relevant logs and/or screenshots

The curl call is here in our build script
