Hello @Horus-K, Thank you for reporting the issue. To assist us in diagnosing and resolving the problem, could you please share the following information:

The detailed Netbird status from both nodes using the command: netbird status --detail

Additionally, provide the firewall rules from the node where the attempted ping occurred. You can obtain this information with the command: sudo nft list ruleset.

@Horus-K, we asked a few more questions via Slack; it might be better to troubleshoot there.

PavelNiedoba commented 7 months ago

Nobody else will benefit from slack advice, google does not index it and slack free account does not show anything older than 3months

vulndev commented 6 months ago

I have the exact same Problem: Mobile Devices can not connect to devices which are not directly accessable over the internet e.g. behind a firewall. The TURN server seems not to step in and it might be because of this error:

ERROR: check_stun_auth: user self credentials are incorrect

The username and password in management.json and turnserver.conf are the same. I checked them also within the containers. If there have been a solution for this problem here it might help me also.

vulndev commented 5 months ago

I troubleshooted the problem and found out, that my problem was the coturn server which is also placed behind a NAT gateway with dynamic ip addresses. Therefor the external_ipparameter in /etc/turnserver.conf can not be filled but should be. I wrote a little script which updates the external_ip statement whenever the public address changed:

#!/bin/bash

# path to turnserver.conf
TURN_CONF="/etc/turnserver.conf"

# get external ip address
EXTERNAL_IP=$(curl -s ifconfig.me)

# read current ip address from turnserver.conf
CURRENT_IP=$(grep "^external-ip" "$TURN_CONF" | awk -F"=" '{print $2}')

# check if public and current ip address differ
if [ "$EXTERNAL_IP" != "$CURRENT_IP" ]; then
    # set new public ip address
    sed -i "s/^external-ip.*/external-ip=$EXTERNAL_IP/" "$TURN_CONF"

    # restart coturn
    systemctl restart coturn
    echo "Coturn was restarted with a new external ip address: ($EXTERNAL_IP)" | logger
else
    echo "The external ip address has not changed." | logger
fi

Whomever this may help.
