Windows 11 requires SMB signing by default, which stops it connecting to public (guest) folders shared from HexOS. Turning that requirement off on the Windows PC restores the connection.
Warning: This lowers the security of SMB connections from this PC to every server it talks to, not just HexOS. On a home network that is normally an acceptable trade-off. Avoid it on a shared or corporate machine, and prefer connecting with a user account instead of a public folder where you can.
Pick whichever method suits you — they all make the same change. You need administrator access on the Windows PC, and a reboot afterwards.
The quickest option, and the easiest to pass to someone else.

Info: The
-Forceflag skips the confirmation prompt. Leave it off if you would rather confirm the change yourself.
Available on Windows 11 Pro and Enterprise.
gpedit.msc, and press Enter.Help: Still cannot connect after rebooting? Check that the folder is shared and that you are using the server's IP address, then ask in the HexOS Discord Community.
