this issue is related to server/redis, NOT nodebb itself.
I have created dedicated Redis (3.0) cluster via Azure portal and seems to working fine from the 1hour.
I need to add rest of the plugins and check if they are not cause any issue but seems that problem was with the server/newest redis
npm install installs everything in package.json but we have different dependencies based on what database you pick during node app --setup (redis, mongo, level). Usually just running npm install is enough but in this case there were changes to the database dependencies.
