Hi,
I'm new to ubuntu and am struggling to find out why the last couple of days my dongle has been getting ICAP protocol errors and now am getting Unable to determine IP address from host name "apps.facebook.com".

At the bottom of the page on the errors am getting CSIN code: pg-bproxy1-3 ERR_DNS_FAIL

All the info on the page is:

ERROR

The requested URL could not be retrieved


The following error was encountered while trying to retrieve the URL: ?????????????????
Unable to determine IP address from host name apps.facebook.com
The DNS server returned:
Server Failure: The name server was unable to process this query.
This means that the cache was not able to resolve the hostname presented in the URL. Check if the address is correct.
