Pattern update and Synchronization not working after SFOS 16.05.4 MR-4 update

Upgraded to MR5 and more than 12 hours no dns issue

No luck with MR-5 on XG 210.

After 15 hours Pattern update ans synchronization not working and users are not getting websites.

Hi Vishvas,

First, Verify the time settings on the XG appliance. Now, take SSH to the XG and go to the option, 5. Device Management > 3. Advance console. Execute, the below command and then do a manual pattern update from Back  & Firmware | Patterns | Update patterns now.

cd /log

tail -f u2d.log

Follow the same steps and check the licensing.log after doing a manual synchronize on the XG device. DM me the captured logs to investigate further. Finally, show me an output of "ping 8.8.8.8" and "nslookup sophos.com" from the advance console. 

Thanks

Hey sachingurung.

DNS stopped working again. And it seems, that DNS server gets killed if a VPN Cisco connection is opened. Check this thread, which DomNik initiated: DNS Server stops working for LAN Zones after Cisco VPN is established . I tested it just now and can confirm the problem.

It would be great to see whether you too can replicate this behavior or potential root cause.

Thanks

Hi Norbert,

I will certainly investigate it internally. Provide me some time but, please raise a new thread and DM me the link.

Thanks
