Corona Integration malfunctioning after HA restart

Hi,
in my setup im using the corona integration, but since a few months it loses its data after i restart HA and is corrupt. Im using the sensors for germany, for testing purposes ive also configured worldwide, but same issues. I have to remove the integration, restart HA and then readd the integration. If I try to readd the integration without HA restart, I get this error in the logs: https://gist.github.com/Tenn0/ba65c855975dd811a552e73534d0a665
I tried to reproduce the error to get the logs for the reason, why the integration is failing, but of course the integration “survives” a few restarts. I´ll give you the logs, once that happens again.
