I am not sure even where this error is coming from. :
Squeezebox Error 'HTTP Error 404: Not Found' in module 'request.py', method 'http_error_default'
Failing statement [line 643]: 'raise HTTPError(req.full_url, code, msg, hdrs, fp)'
Seems to be related to Squeezebox plugin, but I am not sure what request.py even is. It's not part of the p[lugin so am am not sure how to trace. The Squeezebox is playing and active. One thought I have is that my squeezebox runs under 192.168.1.12:9000 but the plugin insisted on using port 9090. Its seemed to work OK for a bit, but then this error started to come up every 2-4 minutes (from looking at logs). Any ideas?
