I have a tedious problem with Acrobat Pro X 10.1.3.23: when I want to apply a timestamp to a document I always get that error.

I have configured VeriSign TSA server http://timestamp.verisign.com/scripts/timstamp.dll and it returns that error. I have tried Comodo CA http://timestamp.comodoca.com/authenticode and Aruba https://servizi.arubapec.it/tsa/ngrequest.php but all three returned the same exact error. My PDFs are now signed without a certified timestamp and this is a problem for me.

I'm obliged to sign documents and apply a certified timestamp at the same time.

This seems to be a common error in Acrobat, but I found no solution to it.

Can somebody help me?

[Update] Thanks to Wireshark I found this

The time stamp server is not free of charge. So, this servers reject your request. you can use free time stamp servers.

Can you give an example of such a free time stamp server that djechelon is able to solve his problem? –  FiveO May 1 '13 at 14:43
    
AFAIK Verisign's TSA is free of charge. And Aruba is not free of charge but I have paid for that! –  djechelon May 1 '13 at 15:25
