Can't Connect to openvpn-as

Hello,

I’m trying to setup an OpenVPN Access Server with the linuxserver.io docker image.
I used the following guide:
https://docs.linuxserver.io/images/docker-openvpn-as

I could login the admin panel and download the config file via browser.
When i try to connect i get the following error:

TLS Error: cannot locate HMAC in incoming packet from [AF_INET]my.ip.address:1194

Does anyone know why i can’t connect?

Thanks for your Help!

My Server config:

On startup, wait up to n seconds for DB files to become

available if they do not yet exist. This is generally

only useful on secondary nodes used for standby purposes.

Normally set to 0. If you have multiple, independent AS instances

running on the same machine, each should have a unique unit number.
