I see the following error in the web console of openems UI hosted by consolino. You can see localhos:8085 which seems to be typo somehwere.
main.efa841b278915fe9.js:1 Mixed Content: The page at 'https://openemsuilocal.consolinno.de/index' was loaded over HTTPS, but attempted to connect to the insecure WebSocket endpoint 'ws://localhos:8085/'. This request has been blocked; this endpoint must be available over WSS.
I guess thats because https://openemsuilocal.consolinno.de/index needs to connect to YOUR local machine and not to the localhost running the UI right now. So i guess it is as expected.
