On the Citrix StoreFront Server (Server 2008 R2), in RemoteApp Manager, the Digital Signature Setting did not have a certificate assigned. I set it to use the storefront self signed certificate and apps now launch externally. Go to the full post
Laban Milyard Members #1 Laban Milyard 6 posts Posted 17 June 2015 - 07:29 PM Just finished an installation of Xenapp 7.6 with Netscaler 10.5. I am able to login and am presented with a list of apps.

Protocol driver error within a Citrix environment can mean so many things. But it comes down to this: the client cannot find the server. So if it were up to me, I’d change this message to ‘The ICA client cannot connect to the XenApp server’, or even sorter; Cannot connect to the Server. Troubleshooting cannot connect ‘Protocol drive error’ can have so many causes, and here’s a list of things you should check. 1 - Step one is to determine what the problem is, we split that up in 3 groups; client, the workstation or thin client transport, network cables/switches/firewall server, XenApp server/load balancer To determine which is your case is usually fairly simple: How much people have the problem?; 1 – usually the client 2 to department size (50-100) – usually cannot connect to transport (network) All people cannot login; usually server problems These figures are indicative, it is very well possible they don’t count in your case! 2 – Client problems Here’s a list of things you could check; is the network cable connected Is the network driver properly installed check your IP configuration check for blocking software like firewalls check for viruses check your ICA client version Sometimes it faster and easier to just replace the whole client, specially with thin clients. Or sometimes a reinstall is faster than troubleshooting. 3 – Transport problems At one of the faulty clients; check the IP configuration; check network card physically, cable, link LED, follow the cable to the outlet. check the default gateway, see if you can ping the default gateway check the DHCP settings try to resolve one of your XenApp servers at the client ping one of the XenApp servers Use telnet or putty.exe to see if the port is blocked somewhere during transport, do a: C:> telnet ctxsvr01 1494 If the ICA protocol is listening you should get a black empty screen, with a few ‘ICA’s appearing. If not, this means that either the server is not listening on port 1494, or some network component is blocking traffic on this port. This is usually a firewall, so contact your network administrator if you suspect t
2013 When using Citrix Presentation Server 4.5 one day you may be welcomed with the following message when trying to open a hosted application: Unable to launch your application. Contact your help desk with the following information: Cannot connect to the Citrix XenApp server. Protocol Driver error. As described in Citrix KB article CTX136826 this can be fixed by recreating ICA-tcp listener in TS configuration. However, as noticed by my colleague Artur, one can make it work by simply disabling and re-enabling this listener. No need to delete and re-create it! Hope that helps someone.

The error is on the server side. aaron pisze: 11 marca 2016 o 06:51 If it is a client side problem (i.e. not all clients experience the issue), then check the user's proxy settings in their browser or try a different browser.
