Updater failed: unreachable: /tmp/crl.pem: No such file or directory

This morning, I had bad internet, like problems with PS4 network, and slow internet. I resetted the modem of the provider and the turris router. But still not working.
Now I got this message:
"

Error notifications

Updater failed:
unreachable: /tmp/crl.pem: No such file or directory
"

It was send just 45 minutes ago from ":turris@notify.turris.cz" to my email address

I see this kind of error notification regularly. But sometimes updates seem to work. Is there something I could do so that the updater does not fail? Maybe internet problem and updater failing are related?
This is the problem: I never know if the provider is causing this, or the modem of the provider, or the Turris router.

Internet should work. Did you try to check your connection in Foris? Or did you try to enable/disable forwarding?

Updater thing is not related.
