netbird conflicts with adguardhome on ubuntu 22 server

I think I spoke too soon!!
On a detailed check, it was my custom dns config in netplan config seems to be the cause.
The nameserver entry was set to my lan router IP instead of 127.0.0.1, while I was testing something else. Reverted it, then 'netplan apply'; all good now. Thanks.

I have tried many ways to fix the issue. My observations:

1. On reboot, adguardhome docker starts okay.
2. Once the netbird service starts, that docker exits. Can see error related to 0.0.0.0:53 port not available.
3. 'netbird down, start the docker manually, all okay.
4. Disable netbird service, and, reboot.
5. adguardhome docker start for a moment, then exits, error: port conflict.
6. added 'ExecStartPre=/bin/sleep 30' to /etc/systemd/system/netbird.service, then reboot.
7. Same result as step 5.
8. If I disable 'Nameserver' on the management server/DNS/Nameservers page, all works normal.

Looking for ideas to fix this.

Have you looked into the --dns-resolver-address CLI flag or NB_DNS_RESOLVER_ADDRESS env var: https://docs.netbird.io/how-to/cli#up

For the time being I have tweaked the Nameserver - Distribution groups, and Access policies, and made it to work. In short, the DNS will not be applied to the adguardhome peer.
Not sure, if that made it work!!!
Will try for a few days and see.
