What happened?

I am running netmaker since 5 months on 0.16.3. Yesterday I updated everything on 0.17.1. 5 out of 6 clients updated fine and reconnected to the api. One client is still having issues.

There are two other clients within the same physical network without problems.

running on debian 11, installed via netclient repo.

things I did:

stop netclient
rm -rf /etc/netclient
apt install --reinstall netclient
delete node from dashboard
reenter old network with same name
create new network for node

all the same outcome.

Version

v0.17.1

What OS are you using?

Linux
