Well, It's definitely is not a Meraki issue, so I suggest you to remove the connection then create a new connection.
Also, you can find Powershell scripts to configure the client VPN connection here:

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.
