Hi Javier,

There unfortunately could be a number of different reasons for this, some related to DataMiner and others on external factors, such as network connectivity, etc.  Probably the first place to start your investigation is to investigate if:

• This happens on just one machine, or multiple? One machine would rule out systemic issues, but if it is happening on all machines that indicates a potential DM issue.
• Also, can you access Cube on the DMA itself? If so, DM is running, but the connectivity is likely an issue.

You can also look at the logs on the server in the folder C:\Skyline DataMiner\Logging. A few logs you might want to check for any sort of anomalies would include:

• SLDataMiner.txt - provides general information on the status of your Dataminer server.
• SLErrors.txt - a consolidations of error logs that might shed some light on issues that could be contributing to this.
• SLWatchdog2.txt - can contain messages for critical issues with DataMiner. Search for "RTE". If you find any Open or Half Open RTEs, that is a sign of potential SL processes issues and a restart of DM is likely necessary.

That said, if you are able, you could also try restarting the DataMiner services from the server by right clicking on the Skyline Task Bar utility ( ) and selecting Restart DataMiner. Alternately, you could even restart the server.

Hope this gets you started. Good luck!
