You management VLAN is misconfigured.
By default, the switch will try to contact Meraki Dashboard on the untagged (native) VLAN. Alternately, you can specify the management VLAN under Configure > Switch settings. This allows the switch to reach the internet via a trunk port.
I am not a Cisco Meraki employee. My suggestions are based on documentation of Meraki best practices and day-to-day experience.
Please, if this post was useful, leave your kudos and mark it as solved.
