Hi,
Home install of UTM 9.711-5 64-bit
Just recently I've noticed that I'm seeing a lot of name="web request blocked" action="block" error="Connection to server timed out" entries in the web filtering logs. 99% of the time they are preceded by a log entry saying message="Write error on the epoll handler 82 (Broken pipe)".
These are appearing on domains that are in the proxy exception list, and some (not all) are reachable if I browse to them directly, and have only started appearing in the last week or so. I don't see any significant changes in the configuration audit over the last month.
Can anyone help on where to start troubleshooting this?
