CM went off line for about 45 minutes - why?

rfcat_vk

Hi folks,

any reason why CM went off line for about 45 minutes? My XG shows failed attempts every 5 minutes for about 45 minutes. The XG was online with DDNS updates and user activity the entire time.

    I haven’t checked cm logs just my XG logs which showed fail to upload to cm only.

    I will check cm logs shortly.

    Hi Vishal,

    the CM logs basically show the same as the XG, failed to communicate, no more details.

    The issue also occurred on the 21st June.

    Hi Ian, 

    Share the log output if you see any suspicious log entries for the time when it was failing to connect.

    If no suspicious logs, then we need to monitor drop packet capture, tcpdump and the PCAP for the IP of CM.

    You can get CM IPs by resolving the URLs found in the CM logs.

    The answer might be one of the Devs was using my backup on a test system that accidentally connected to the internet?

    Hi Ian, 

    It could be but how did you find out about the Failed attempts? Did you go through the logs or any firewall notification?

    Hi Devesh,

    I received emails with strange details all referring to my XG by fqdn. I checked the XG and cm.

    The details explain to me why my XG was showing offline a week or so ago with a strange IP address. I think Harsh and Emmanuel are investigating.
