Pydio Cells start - A few errors with a merger

Hello!
I have a problem. When I started pydio cells in my virtual machine (Ubuntu) I will get errors - ERROR pydio.grpc.config (error: nats: invalid connection) or Storage is not available. Index not reachable also appears. What may be the problem? I have the latest version of MySQL database

Hello @mateo3235 and welcome to the forum.

Could you precise your mysql DB version number (latest might vary from a system to another…)

And after the system is started, can you log in or not ?
Did you get any error message during install ?
When do you see the message you are talking about ?
