I found the error message that "Unable to fetch configuration" in one of the stacked Cisco Meraki MS250-48FP switch. What will be the cause for this issue and how to rectify this. Another switch in the stack is working fine.
Usually this occurs because of lack of connectivity with the internet and even after running again the internet takes a long time to clear the alert. This same problem occurred to me already, and the same one back to work.
