Issue with device going offline

asked 2020-01-28 11:04:01 +0000


We have an issue with a 3 devices connected to the same server going offline each night at around 9 pm. 2 out of 3 devices one night stayed online all night today all went offline during the night have ran a Wireshark overnight to see what could be causing this but not 100% sure when looking at the logs. From what I can see it sends through a [SYN] from device to the server then server sends back a [SYN, ACK] then the device response with a [ACK] then it sends a heartbeat through to the server to show it's still online and then server responds with HTTP/1.1 200 OK but then straight after the device responds back with a [RST] in a red line. This seems to be the only errors I can see when filtering against the devices IP

Making a baseline capture of situation normal may help for comparison.
What is meant by "offline" and "online"?
Disabling the color rules in Wireshark will get rid of the red line. RST does not always mean error.
