A "background job error" indicates a problem with things that Awasu runs in the background e.g. auto-generating reports, downloading enclosures, etc., not specifically something to do with updating channels.
However, the background job is probably failing for the same reason that your channels are not updating. Can you run Awasu again and try to update a bunch of channels, some that fail, some that work OK. Then send us the following files:
- C:\Program Files\Awasu\Users\YOUR-NAME\config.ini
- C:\Program Files\Awasu\Users\YOUR-NAME\Logs\AwasuActivity.log
- C:\Program Files\Awasu\Users\YOUR-NAME\Logs\AwasuError.log
The fact that feeds coming from awasu.com are OK but everything else is not suggests that there might be a configuration problem with your proxy - it's allowing requests coming from awasu.exe to access anything at awasu.com but nothing else.
