Hi there,

It seems like that you are getting an HMAC error, I could suggest making sure that you’ve followed step 7 from the tutorial that you’ve shared.

Alternatively, I could suggest using this 1-Click installation image for OpenVPN instead:

https://marketplace.digitalocean.com/apps/openvpn-access-server

That way you will not have to do any manual configuration.

Regards,
Bobby
