If you are using the Data Collector in an auto-caching server environment, the data collector service will need to be restarted because the proxy server information will change. The frequency of the proxy information changing could be as often as every hour/day/week/month.

How the Data Collector works with Proxy:
When you start the Data Collector it will automatically detect the current proxy server and then the Data Collector service will start with the specific proxy server detected and the defined user account with appropriate rights to access the internet through the proxy server. When the Data Collector is running it will not detect if the proxy server is changed.

If then the proxy server is changed and the Data Collector is not restarted then it will give the error message “Data receiver Temporary Offline” because the Data Collector is still using the proxy server when it was started the first time.

As the Data Collector contacts the server with an interval of 30 minutes, there can be a delay on maximum 30 minutes before the message “Data receiver Temporary Offline” is received.

When the Data Collector is running it will not detect if the proxy server has changed.

To detect that the proxy server is changed then the Data Collector need to be restarted, this is by design. 

Please remember, if you use proxy server then you also need to defined a user account with appropriate rights to access the internet through the proxy server in the Data Collector service.
