Can you give an example? I am looking for a way out.

I kind of self hosted for decades on a virtual server until I couldn’t keep up with it. So much stuff broke something in the stack, bringing the server down. Often, I had to initiate a full lock down on everything before going up again, consuming a day’s effort or two.

I don't know exactly what you are looking for. But dropbox for cloud storage. Proton for email. There are options around.

Hetzner offers managed nextcloud and storage instances.
