I have a samba share running on my server (just an Intel N100 Mini PC). It’s running Fedora Atomic and my desktop is also running Fedora Atomic.
While it’s good enough to watch videos on, reliability when it comes to uploading files to it has been very poor. The connection ends up timing out after a few minutes of uploading.
I found that using rsync to upload files to it has been a lot more reliable.
If it’s both *nix, why not NFS? Even Win10 with UTF-8 works well with my NFS server. These days my SMB server is only for Win7 and Android.
If you force turn off SMBv1, should work with win10/11
I have a mix of nfs and smbv3 shares with linux, mac, windows machines. Use nfs for video/music sharing for all. SMBv3 for protected private files.
Edit: i read your comment wrong.
