If you have connection difficulties and you are part of a medium – large enterprise this information may need to be forwarded to your Information Technology / Information Systems Engineers so that the vistime client can connect to the vistime servers on the live internet.
We have attempted to ensure that vistime will work through almost any firewall configuration, however as every network is different and some corporations have stronger and custom configured networks (for good reason) some settings may need to be changed at the corporations site where necessary.
Proxy Servers
By default the vistime application will check online for updates over HTTP (port 80) to a dynamic php page, this is done to prevent caching of the page so that the clients update in proper fashion. The vistime client will also pull from the registry (if possible) the systems’ default browser and will use that browser’s user-agent for all HTTP get requests. Where this information is not available vistime will use the Firefox user-agent.
If the connection is blocked or is transformed from the proxy server in a way that renders the data unreadable by the vistime updater an update error will be displayed. This can be considered a critical error as when a vistime update is released all clients must run the same version to prevent incompatibility issues.
If possible any request to the vistime.com domain should be white listed from the proxy server, if that is not possible then a list of IP Addresses that the vistime client may connect with directly can be obtained from the vistime support team, please email support@vistime.com and request for this information.
Firewalls
Vistime will connect on the following ports, please ensure that the client can make a connection outward and that data can be returned.

This must be enabled on your network in order for a successful connection to the vistime network, under most to normal circumstances this shouldn’t be an issue.
