Unlike the similar question, I cannot even connect with smbclient.
The samba share works fine in windows and automagically works, but in Linux I can't mount it at all and the error message is cryptic at best. Here is my samba.conf:
[global] dos charset = CP437 netbios name = REDACTED server string = Lab server role = standalone server map to guest = Bad User obey pam restrictions = Yes smb passwd file = /var/etc/private/smbpasswd private dir = /var/etc/private max log size = 51200 server min protocol = SMB2 time server = Yes deadtime = 15 max open files = 11070 hostname lookups = Yes load printers = No printcap name = /dev/null disable spoolss = Yes dns proxy = No pid directory = /var/run/samba panic action = /usr/local/libexec/samba/samba-backtrace idmap config * : backend = tdb acl allow execute always = Yes create mask = 0666 directory mask = 0777 directory name cache size = 0 kernel change notify = No map archive = No map readonly = no store dos attributes = Yes strict locking = No [common] comment = Lab Common share path = /mnt/pool/common read only = No inherit acls = Yes hosts allow = XXX.XXX.XX.X/24, XXX.XX.XX.X/24 <-- redacted hide dot files = No veto files = /.snap/.windows/.zfs/ vfs objects = zfsacl, streams_xattr, aio_pthread zfsacl:acesort = dontcare nfs4:chown = yes nfs4:acedup = merge nfs4:mode = special recycle:subdir_mode = 0700 recycle:directory_mode = 0777 recycle:touch = yes recycle:versions = yes recycle:keeptree = yes recycle:repository = .recycle/%U
The error message is:
[as@localhost ~]$ sudo mount -t cifs -o username=removed,password=removed //server.ip.address/common /media/windowsshare/ mount error(95): Operation not supported
A perfectly useless message.
The debug-enabled dmesg:

I have tried many different
-sec options---they all fail, everything has the same error message. smbclient is not helpful either:
smbclient //184.108.40.206/common -U username%password protocol negotiation failed: NT_STATUS_INVALID_NETWORK_RESPONSE
How does this work on windows but not at all on linux?
