I found some way. I send to here for discussion to fixitReason: malware enabled on my FW rule to handle endpoints, using the sophos engine. Sometimes the sophos AV pattern update fails. When this happens, it breaks access to the web. if turn it off it fixes
Some way I find on Internet, I send here to disscuss
Note: I do nothing any of the methods below
tail -f -n200 /var/tslog/up2date_av.log
# Solution 1Try to stop and restart AV service?
# Solution 21. "mv /content/u2d/pattern /content/u2d/pattern.org. This will rename the pattern file to pattern.org.2. Now update the pattern files with the GUI using System > Administration > Updates.
# Solution 31. change the malware engine from sophos to Avira - in the GUI under System Service --> Malware ProtectionThat should temporarily fix the problem.2. Just run the command mv /content/u2d/pattern /content/u2d/pattern.old3. click update the patterns in the GUI again, that pattern file should be recreated.4. don't forget to change back to using the sophos malware engine.
