Device unable to connect to server or network

Please provide more - indeed, any - details of what it is you're trying to do.

that's such a generic error message, it doesn't give anyone enough context to understand the problem or suggest a course of action.

Where are you seeing this message?

What app are you using?

Did it work in the past and isn't now? or it's never worked?

More details please.

Are you running a Mac with the macOS Server operating system installed? If so, which version?

ButI’m going to guess you are not looking for help with managing a server here, so the following is a discussion might well be relevant: Your device couldn't connect to the serve… - Apple Community

And for completeness: update to (macOS, iPadOS, iOS) 26.5.2, remove any add-on VPN apps (remove the apps, as disabling add-on VPN apps doesn’t always reliably disable them), restart whatever gear you’re using here, and see if things work better.
