SEA cant connect to sea-dynamic.sophos.com; threat definitions not updated

Hi All,

Email appliance is having trouble connecting to sea-dynamic.sophos.com

When I tried pinging sea-dynamic.sophos.com the result is:

Pinging sophos.vo.llnwd.net [203.77.191.0] with 32 bytes of data:
Request timed out.
Request timed out.
Request timed out.
Request timed out.

I'm currently using 8.8.8.8 as my DNS:

203.77.191.0 <--- this is a network address.

Does anyone here having the same problem as mine?

Have you got into any solutions?

Thanks,

tech
