Sophos XG Firewall - Internet Outage

Kuldev Admin

Hi,

Recently in my company we have had problems where the internet has stopped working and as a request we have had to reboot the firewall (Sophos XG V18) in order to resolve the issue. It happened last month and it happened again last week. I have logged into the Advanced shell and looked into the error_log.log file which is on the log directory. The only error we I can find which matches the timestamps of when the internet outage occurred is the following:

AH01909: manage.cyberoam:65004:0 server certificate does NOT include an ID which matches the server name

Can someone explain to me what this means? Is there any where else I can be looking for any other logs that are relevant?

 Thanks

    Hello there,

    Thank you for contacting the Sophos Community.

    The logs to check for this type of issues are:

    csc.log, applog.log, syslog.log, mysnc.log and networkd.log

    Additionally, check the Memory and CPU graph from Diagnostics >> System Graphs

    Also check if you have any coredump under /var/cores

    If the issue persists, I would recommend you to do the following:

    Connect computer to COM port on firewall using a micro-USB to USB cable - micro-USB end connects into the firewall

    In Device Manager, confirm the COM port number assigned 

    In PuTTY under Session > Logging, set Session logging to "All session output"

    Configure where the log file is being written using the Log File Name field

    Connect to firewall using serial connection type, with COM port identified in step 2 (e.g. COM3), and speed set to 38400

    Leave computer powered on and connected until issue next occurs
