My VPS becomes unavailable from the internet few times a day for a couple of miniutes

Hi! My VPS becomes unavailable from the internet few times a day for a couple of miniutes.

I was unable to detect what is the root of the problem. The VPS runs web services in docker. each stack is cloudflare tunneld. When shit hits the fan cloudflare also detects their tunnel down. This means the tunneled container also cant get out to the internet.

While Im also unable to ping or SSH the public IP of the VPS.

The VPS does not stop or reboot. It simple becomes unavailable couple of times every day. This happens for almost 2 weeks now since I noticed first. Very likely to be a networking issue.

Please help me localize and fix the problem.
