Front Panel of VI Doesn't Show When Client Tries to Run Remote Panel on Server

Primary Software: LabVIEW Toolkits>>Internet Developers Toolkit
Primary Software Version: N/A
Primary Software Fixed Version: N/A
Secondary Software: N/A

Problem:
When I open a remote panel the VI shows one of the following:

• A broken picture link instead of a front panel
• An error message saying, Your internet address (hostname) is not allowed to retrieve documents from this server.
• An error message saying, Client does not have access to specified VI.

How can I fix this?

Solution:
This is caused by one of three things:

• The server is not configured to allow the correct VIs to be accessed by remote panels.
• The server is not configured to allow the client IP address to access the VI.
• The run-time engine version of the client does not match the run-time engine version of the server. (Example: client is using 8.0 and server is using 7.1)

To configure the server to allow the correct VIs to be accessed by remote panels and also to configure client IP addresses you must configure directories and network settings by selecting Tools» Options» Web Server: Configuration and Web Server: Browser Access.

Under the Web Server:Configuration category, you must make sure that the Enable Web Server is checked. In the Web Server: Browser Access category, you must specify a list of client IP addresses that are allowed access to the web server. The link below describes in more detail how to correctly configure both server and client to avoid experiencing this issue.
