Symptoms
After selecting the project in Web Capture Station or Web Scanning Station, the error "Error connecting to <server address>" is shown.
Cause
In most cases, this error indicates that the proxy is used in the environment.
Resolution
Web Capture Station and Web Scanning Station use the Scanning Plugin to load images. The Scanning Plugin of the FlexiCapture 12 Release 3 Update 3 (and versions before that) does not support proxy. The proxy support in the Scanning Plugin is planned for FlexiCapture 12 Release 3 Update 4.
You can check the actual version of FlexiCapture by using the following links:
This issue can only be worked around by proxy settings: exclude the necessary computers/users and FlexiCapture server addresses from the proxy.
