Could someone tell me why adobe reader can't parse the timestamp in the not working one?

I had the same problem with the pdf signature timestamp…..
The thing I was doing wrong was the SHA-1 hash sent to the timestamp server, more precisely I was sending the whole signature SHA-1 hash when I suppose to send the SHA-1 hash of the RSA encrypted hash of the digital signature (I think that in your case is the 256 hash starting from 1783).
Hope this helps you,
thanks you helped much!I did not have the exact same problem as you, but I managed to find my bug: apparently the opposite of yours. I calculated SHA-1 hash twice (the TS request goes through multiple layers of services in our framework before it is actually sent to the TSA. We accidentally calculated hash in two layers, so the hash became invalid. Very tricky bug to find.)
