To Reproduce
Steps to reproduce the behavior:

Try to configure a OpenVPN over Cloak using defaults.

Expected behavior
The client should be able to execute the binary

Smartphone (please complete the following information):

• Device: Nokia 6.1
• OS: Android
• Version: latest

Server (please complete the following information):

• OS: 64bit lite image from official rpi image tool

Additional context

While the docker file seems to download the wrong binary for the ck-server, the url pointing here has the right binary. https://github.com/cbeuw/Cloak/releases/download/v2.5.5/ck-server-linux-arm64-v2.5.5

This is the version supposedly used in the Dockerfile. After exchanging the binary with this one, you can go on the client to update the config of the Cloak server and restart it. It will restart properly. If it doesn't it might be necessary to manually generate and add the private key in the config file in /opt/amnezia/cloak/ck-config.json.

What's strange is that technically the url I used and the one used in the Dockerfile should be the same. So maybe the Curl corrupted the file somehow or there would need for a checksum to check that the file we downloaded is the expected one?
