Citrix Client Connection - PN Agent 10.150

Dear all,
we have Citrix PS 4.5. in one of our office. office2 connect to it via WAN  wiht PN Agent 10.150.  office3 have not problem at all, and connect same way. See pictures below.
Also this error only happens when i entered the Citrix server name (host name) on the SERVER URL on office2 clients machines. However, when i entered the IP of the citrix server it pop ups agent for users credential on client machines.
we have not made any changes on WAN Routers.
any though is greatly appreciate.

PN Agent 10.150 has performance issues and Citrix release a new version quickly.   I recommend upgrading the client(s) to 11.0.    You will be able to do a in-place upgrade so you don't have to reconfig the client.

10.15 was a major pain for me back when it was originally released.   I had to go bad one version to clean up the issues.

11.0 client:

Still same issue i have to type  the server IP on the SERVER URL if i type the host name it does not work out http://servername/Citrix/PNAgent/config.xml

Sounds like your name resolution is not working.    Can you ping servername and do you get back or does it not resolve?

yes i can ping this server by hostname and IP
i think it is more likely some dns protocol not passing to the other side of the WAN.
WHAT procotol are these? any thoughts?

ICA which is TCP 1494

But if you able to get to it via IP there is something else going on

What if you put in http://FQDN/Citrix/PNAgent/config.xml

Make sure the dns record points to the same IP that your entering? Try the FQDN. I would also try https://FQDN/Citrix/PNAgent/config.xml. does this server have any nating inplace? Does the server have an altaddress that could see the client IP and assign a nat address?
