It helped me a lot. Thank you :)

I've added my experimental load balancer to this list. Hopefully, the first URL should "just work" for most applications like Adobe, but you can specify the type of service by appending it to the URL too.

This http://tsa.starfieldtech.com/ doesn't work anymore

You're right, thanks. Removed it from the list completely.

@Manouchehri Thank you. I think the list should also not contain the following as they are not working anymore

You are correct. My team had already removed those from our rfc3161.ai.moda load balancer, but I forgot to update the list here too.

http://ts.ssl.com

Is there link to certificate(s) that are used for the TimeStamp? We need to put them into trusted list.

Found here: https://www.ssl.com/how-to/install-ssl-com-ca-root-certificates/

Do https:// URLs actually work for anyone with signtool? I'm getting:

SignTool Error: Invalid Timestamp URL: https://...

Both for signtool /t and for signtool /tr.

@JohnPlanetary

I've tried the https:// url's and no, it is not working, it appears the same error.

SignTool sign /fd SHA512 /a /f certificate.pfx /p MYPASSWORD /td SHA384 /tr https://timestamp.sectigo.com c:\sign\MyProgram.exe
SignTool Error: Invalid Timestamp URL: https://timestamp.sectigo.com

The good news is that the http:// still works fine, and most common TimeStamp servers don't even have the https:// version working at all.
But I'm sure the https version did work fine on the past, some update to Windows must have messed up things.

I've had the Windows SDK signing tool 10.0.19041.0, but even in the latest 10.0.22621.0 that I downloaded from: https://developer.microsoft.com/en-us/windows/downloads/windows-sdk/ still doesn't work, so isn't just a question of updating the tool, unfortunately something else probably needs to be changed by Microsoft.

My http://rfc3161.ai.moda load balancer should work fine over HTTP. I didn’t add it to the list because I want to encourage everyone to use HTTPS, but it works fine if you must use HTTP.
