comodo timestamp server

Hello. I’m very new to coding and certificate signing so would like some help please.

I have been using the timestap for ages, by copying and pasting the command line editor. My code has suddenly stopped working today. I’m trying to sign my .exe with this command line

signtool sign /tr /td sha256 /fd sha256 /a C:\Users\work\builds\App-Setup.exe

and I get the following error

SignTool Error: An unexpected internal error has occurred.
Error information: “Error: SignerSign() failed.” (-2146869243/0x80096005)

It has been suggested to me that the timecode server could be having an issue? I haven’t changed anything since the last time stamp about a week ago.

Any suggestioin would really be appreiciated.

Thank you.

I’ve sorted it now. I needed to uninstall and reinstall the authentication client. Now the Comodo ca timecode is recognised.

Thanks everyone.

It is necessary to check the expiration date of the server very often at the origin of the error (SHA1)

Thanks for this @ZorKas. I’m all sorted now.
