1. error with new peer - "Endpoint =". Endpoint ‘’ is invalid. Same error on QR-scan and import config-file
2. does not add new users to conf. Please, when changing the file, do not overwrite the comments. I use comments for monitoring prometheus_wireguard_exporter
3. does not read from the server settings pre-Up, post-Up, pre-Down and post-Down
