Comment 44 for bug 1754671

Please create the following files (and directories if needed for them):

1. /etc/systemd/journald.d/noratelimit.conf containing

RateLimitIntervalSec=0
RateLimitBurst=0

2. /etc/NetworkManager/conf.d/debug.conf

[logging]
level=TRACE
domains=ALL

Then restart journald:

sudo systemctl restart systemd-journald

and NetworkManager:

sudo systemctl restart network-manager

Then you get the full debug log of NetworkManager via

journalctl -u NetworkManager

After all that, reboot and/or connect to your VPN and do

journalctl -u NetworkManager > log.txt

and attach the log.txt file to this bug report. Do not compress the file and do not package it together with other files.
