File sharing via ethernet not working

[mjsmike]

I'm trying to connect an old MacPro to an iMac so the iMac can access and use the drives in the MacPro. File sharing in turned on on both macs. I can see the MacPro in the sidebar of a finder window on the iMac but when I double click it and enter the password it won't accept it. Also tried clicking on "connect as" but that won't accept any user/password either.

I've done this before on other Macs so can't see what's wrong.

Any ideas?

Version of macOS installed on both cMP and iMac? Post screenshot of your Sharing set up on cMP.

MacPro is on High Sierra. iMac is on Sonoma.

On the MP I've ticked File sharing and Screen sharing for all users.

not sure if this is it, but may get you closer
It looks like high Sierra was towards the end of the of apple supporting AFP (apple's file sharing) and shifting exclusively to SMB (windows file sharing)
from a quick looks like afp is still supported in Sonoma, but depreciated.

you may need to enable SMB on the Mac Pro, might be a different check box for windows file sharing.

in finder, you can force SMB by using "Go --> connect to server" from the menu or cmd-k and type in smb:// and then the IP of the remote computer,
