Signing in 1.7.1 417 error

Hi and stright to the point:
I created a profile for document signing, added the certificate. But when I create a new document with that profile it fails to sign it with a remote server 417 error.
The pdf is createt but is not signed.

I have 2 computers and it works on one but not on the other, both are w7 installs. Cant figure out wat it is.
Any help? thx.


my guess is something is preventing the one PC to contact the remote (timestamp?) server for signing, maybe firewall/security settings?



Hello, is there any solution for offline signing for PCs without internet connectivity or PC behind proxy? I can not access timestamp server directly and signing pdf generates error.
