Reconnecting every ~4.5 hours (v3.10.0-1)

[lv10wizard]

Describe the bug

The container reconnects every ~4h 30m (sometimes immediately after $RECONNECT seconds).

https://api.nordvpn.com/v1/helpers/ips/insights (wrongly?) returns "protected":false after some time.

On my Windows machine connected to United States #8867 via the NordVPN app, curl https://api.nordvpn.com/v1/helpers/ips/insights returns "protected":false even though the nordvpn site says: Your Status: Protected at the top.

curl ifconfig.me returns 23.81.176.114 (the IP of United States #8867 reported by the NordVPN app).

To Reproduce without docker CLI

Run for >5h and check the logs for reconnections.

docker-compose.yml:

version: "3"

services:
    vpn:
        image: bubuntux/nordvpn:3.10.0-1
        restart: unless-stopped
        cap_add:
            - NET_ADMIN
            - SYS_MODULE # For NordLynx (wireguard)
        sysctls:
            - net.ipv4.conf.all.rp_filter=2 # NordLynx
        devices:
            - /dev/net/tun
        environment:
            - USER=${NORD_USER} # From .env
            - PASS=${NORD_PASS} # ^^^^^^^^^
            - TECHNOLOGY=NordLynx
            - NETWORK=192.168.1.0/24

Expected behavior

The container should automatically reconnect only if there is some connection issue, not on an interval.

This is actually a feature and not a bug, i swear,

even if the daemon report that the connection is stable, it actually stalls and every request times out, so I put a mechanism in place to reconnects if a requests to nordvpn API takes longer than 30 seconds, this checks is made ever 5min and can be changed using env variables, Review the readme,

this also happens to me every ~ 4.20h it reconnects, but the container keeps running fine and all the containers in the network are protected at all times.

The real issue is at nordvpn side as far i can tell, the connection just stalls after a while,.there is not much we can do about it.

You could modify the reconnect interval using the env variable to something like a week or so, and after 5 hours get inside of the container and check the status of the daemon/network. Nordvpn daemon seems ok, but all the connections don't respond, we need to reconnect to make it work again.
