I am trying to ssh from my MacBookPro to my Mac but it times out, both are on the same local area network. The same thing happens if I try to ssh from the Mac to the MacBookPro. However I can ssh to either via a RaspberryPi on the same network. I'm confused!
iMac 27″ 5K, macOS 12.6
The problem is almost certainly inside your router. You said it works when you connect to ethernet. You also said you are using a Raspberry Pi. And you are using ssh. Those are all things that people do when they hack around with things. Maybe all you need to do is reboot the router. Maybe it has a stale DNS cache.

The -v output seems to indicate it is the destination Mac the rejected the connection.
A few things.
Boot both Macs into Safe Mode (just an experiment to see if 3rd party software is causing this; 3rd party software is not loaded in Safe mode)

Do you have multiple routers and/or WiFi access points? It is possible the the WiFi access point you are connecting to, is on a different sub-net from the Ethernet connection.
Yes it is a valid IP address, these are the details from the Mac:
And I can ping it from the MacBook:

Does ssh succeed in making the connection, and then disconnect after an idle period?
Or does the initial connection fail?
Are you using a password to connect, or are you using ssh-keygen keys?
If initial connection, does the destination Mac have System Preferences-> Sharing-> Remote Login enabled, and does it allow Everyone or at least your account access?
Are you using a VPN? Some VPNs block local access.
Are you running a 3rd party anti-virus package, or LittleSnitch. Some times these packages block ssh connections.
If it is the initial connection, try
ssh -v -v -v username@host.address
The verbose messages near the end should give a clue.
If you connect, but loose the connection after an idle period, then maybe add the following to your $HOME/.ssh/config file:
Host *
ServerAliveInterval 240
ServerAliveCountMax 2
240 is 5 minutes. Adjust according to your needs, but I would not lower it below 60 seconds.
It's the initial connection that fails.
Both Macs have Remote Login enabled, and the account has access permission - it's the same account on both Macs.
I'm running Avast ant-virus but ssh requests from other computers go through without any issues.
Using the debug options I get:

The target Mac is connected to my network via ethernet and the MacBook is generally connected via WiFi, but if I connect the MacBook to ethernet as well then ssh works in either direction. The IP addresses are different for ethernet and WiFi for both Macs, and also static.
Are you sure 192.168.2.66 is a valid IP address?
I am able to reproduce your Timeout error by attempting to ssh to an non-existent IP address:
$ ssh -v -v -v 172.16.1.222 # <<<---- INVALID IP address (no such device listening on this address)
OpenSSH_6.9p1, LibreSSL 2.1.8

ssh: connect to host 172.16.1.222 port 22: Operation timed out
I also tried turning off Remote Login on the destination Mac, and I get a totally different error (Connection refused):
$ ssh -v -v -v bobm1max.local
OpenSSH_6.9p1, LibreSSL 2.1.8
debug1: Reading configuration data /Users/raharris/.ssh/config

You can find the Ethernet and WiFi IP addresses via
System Preferences -> Network -> Select Ethernet in left column -> Advanced -> TCP/IP (tab)
System Preferences -> Network -> Select WiFi in left column -> Advanced -> TCP/IP (tab)
You can also use the computer_name.local
System Preferences -> Sharing -> Computer Name: abcdefghi
Just under your computer name it should tell you the .local name. You can use that, just like I used bobm1max.local in one of my examples above.
What is SSH?
SSH (Secured Socket Shell) is a secured network protocol widely used by network administrators to access remote computers in a network.
Safe mode on both Macs made no difference. WiFi and Ethernet are on the same subnet, i.e. 192.168.2.xx.
Thank you, that worked! Sometimes just "switching it off and on again" should be the first thing to try.
It is working now, after rebooting my router, but I do appreciate your efforts to help. Thank you.
ssh from MacBookPro to Mac times out
