SETI - BOINC can't access the internet

WCG tasks are reporting ok but I have 4 Seti tasks 100% which will not report, here is a typical message log:
02/02/2012 15:26:51 BOINC can't access Internet - check network connection or proxy configuration.

As you can see I suspended 'fetch work' on Seti to see if this would help but it still says it can't access the internet despite WCG working fine. Are there still issues with the servers being overloaded?

Your BOINC client seems to have problems with http connections, as it can't even reach google (the test site):
