[edit] General
Message Type: Warning Message
This Message means that the BOINC Client Software encountered a network problem and that the BOINC Client Software cannot contact the Project's Server. When I got this message my Internet Service Provider (ISP) was off line and I had no connectivity. So, this error is almost always external to the BOINC Client Software and more than likely is a complete failure of the network system.
Other causes of this error include:
- A failed network card
- The router or modem has lost the configuration information and is not allowing communication.
- The firewall is not allowing connections.
- A proxy is improperly configured.

Line-By-Line Explanation
- The reason we are going to make a Scheduler Request.
- We make the attempt to contact the Scheduler.
- And fail to make the connection because the BOINC Client Software cannot find a translation of the URL into an IP Address.
- This message indicates the exact stage when the error occurred during the communication process with the Project's Scheduler.
- And we exit the communication process.
- This message indicates that we will use Exponential Back-Off to calculate a time interval to wait before attempting to make another try to upload the file to the Project's Scheduling Server.

Line-By-Line Explanation
- Computation for result '(result)' finished
- We completed the processing of the Work Unit and we now have a Result Data File to upload.
- Can't resolve hostname ['(host-name)'] (valid name, no data record of requested type)
- The BOINC Client Software attempts to contact the Project's Data Server, and fails to make the connection because the BOINC Client Software cannot find a translation of the URL into an IP Address.
- Couldn't start upload of '(file-name)'
- Because it could not make the name conversion, the upload failed.
- URL '(url)': error '(error-code)'
- Identifies the URL that was the source of the problem, and the internal Error Code that was returned.
- Backing off 'x' hours 'y' minutes and 'z' seconds on upload of file '(file)'
- This message indicates that we will use Exponential Back-Off to calculate a time interval to wait before attempting to make another try to upload the file to the Project's Data Server.
- Some time later ...
- Started upload of '(file)'
- The BOINC Daemon initiated an upload action with the Einstein@Home Project.
- Finished upload of '(file)'
- The BOINC Daemon completed the data transfer to the Project's Data Server.
- Throughput 'x' bytes/sec
- The measured speed of transfer, in this case was 49,635 bytes per second. This is a fairly high rate of data transfer and is possible as I have a Cable Modem and an "always-on" Internet connection.
