Trouble finding a timestamp service that works

[Imaginative_parent15C2]

Hi

I have a CEP plugin that I need to update. But when I try to sign it with my self signed certificate I get this error: "Error - the timestamp returned from the chosen TSA could not be verified, so the ZXP created is likely to be rejected by other tools. Please recreate your ZXP with a different trusted TSA."

- No ZXP is created.

This have happened before, but I have always found a service that worked. Now however, I can not. I tried http://timestamp.digicert.com and several others, but no luck. Does anyone know of a timestamp service that is still working? Is there any way to sign the plugin without a timestamp service?

I use this line in Command Prompt to sign the plugin: ZXPSignCmd -sign com.mycompany.pluginname com.cmycompany.pluginname.zxp mycompany.p12 ********* -tsa http://timestamp.digicert.com

Thanks,
Jakob

OK. I tried on my mac instead. Worked fine with digicert. So, I'm guessing it must be firewall issue on Windows. I don't know, I'm not an expert in firewalls.
