Environment
RHEL-9.6 kernel - 5.14.0-570.16.1.el9_6.x86_64
VMware vSAN 7.x
Cause
Packet capture revealed that the server should return the error NFS4ERR_ATTRNOTSUPP but it is sending NFS4ERR_BADXDR (Error Code 10036) instead indicating that a file share is offline.
Frame 19: 166 bytes on wire (1328 bits), 166 bytes captured (1328 bits)

Network File System, Ops(3): SEQUENCE PUTFH GETATTR(NFS4ERR_BADXDR)
[Program Version: 4]
[V4 Procedure: COMPOUND (1)]
Status: NFS4ERR_BADXDR (10036)
Resolution
Update the vSAN cluster to ESXi 8.0 P05/ ESXi 8.0 Update 3e followed by vSAN File Service update which contains the fix
Note:
- The vCenter Server managing the Hosts must be at an equal or higher version than the ESXi Hosts version it manages. It is advisable to have vCenter and ESXi on matching Versions as doing otherwise can lead to communication issues between the two as per KB vCenter version to ESXi version (318674) (Refer to KBs Build numbers and versions of VMware ESXi/ESX (316595) and Build numbers and versions of VMware vCenter Server (326316) to determine supported vCenter/ESXi version combinations.)
Additional Information
During the vSAN File Service update the correct version of the VMware vSAN File Service Appliance should get downloaded automatically but if you do not have internet connectivity you can use following URL to download the vSAN FS files
