Citrix / RDC/ Terminal server

The Client system is on an RDC / Citrix / Terminal environment

  • Ask you Citrix/RDP/Terminal Server environment administrator to first install the KeySign Connector Proxy
  • Users can then install the KeySign Connector as they normally would via the link in the pop-up in SigningHub
  • In case users have already installed the KeySign connector before the proxy was installed they will have to re-install the connector

Reverse Proxy

If the Client system uses proxy, the KeySign Connector will not be recognized

Create an exception in your organisations proxy for : ksc.keysign.eu:52183
