Thanks everyone for help
For now everything works like a charm.
What i do:
- Fully uninstalled mosquito and openhab2
- Freshinstalled both
- Made a propper clean config with files. (Migrating MQTT1 items to MQTT2.4 items - #59 by kaju666)
Now cloud is working fine.
Do not know what was the reason, meaby some temporary cloud problem or my temporary isp problem.
