common causes for “There is no Citrix SSL server configured on the specified address.”.
If you’re supporting a secure gateway / access gateway solution for external clients / home working, you’ll already know about this error.
These are some general troubleshooting steps.
This error is always the client that can not resolve / connect to the SSLPROXYHOST value in the launch.ica.
- have a look at launch.ica for the value SSLProxyHost. Is it the FQDN of your Secure gateway / Access gateway? if not => look at your WI settings. On newer WI/clients you might have to disable the citrix browser plugin to be able to rightclick on the published app and save the launch.ica
- check your clients proxy settings. He might have a proxy enabled (because he visited a customer), that is not there. Or he might be at a place where a proxy is needed.
- Firewall restrictions on 443. Even had a customer where there were VLANS with 443 enabled or disabled.
- Check the launch.ica again. If the value proxytype=none => you might experience problems with proxies, pac & dat automatic configuration scripts. Set the Web Interface to auto, use browser settings or automatically detect settings dependent on the WI version.
- Verify if your customer can resolve the FQDN of your CSG/AGW correctly. check your customers hosts file. Maybe the FQDN & ip was set hardcoded in the hosts file. Maybe there is a fixed record in your DNS or the customers DNS.
- There is a known bug in citrix clients < 10.2, where the citrix ica client fails to process .PAC scripts.
