I have an Ubuntu 20.04 LTS server running on Amazon Lightsail. Within the last 4 weeks, the server keeps going offline for a 15-20 min at a time, and then comes back online. Sometimes it happens every 4-5 hours, sometimes 1-2 times a day.

I checked the server logs (in syslog) and found this around the same time as the incidents:

systemd[1]: Starting Refresh fwupd metadata and update motd... systemd[1]: fwupd-refresh.service: Main process exited, code=exited, status=1/FAILURE systemd[1]: fwupd-refresh.service: Failed with result 'exit-code'. systemd[1]: Failed to start Refresh fwupd metadata and update motd. CRON[94256]: (root) CMD ( cd / && run-parts --report /etc/cron.hourly) 

I would appreciate some help in debugging/solving this issue.
