Linux NFS unsupported protocol error after power failure

Everything was smooth until a power failure.
One of my servers and a client are both running Xubuntu 18.04. This server has
internal 4T data disk and an 8T external USB backup drive mounted at /A and /B respectively. The /etc/exports file was unchanged and has these 2 lines:
/A/a 192.168.20.101/24(rw,no_subtree_check)
/B/b1/b2 192.168.20.101/24(rw,no_subtree_check)
Command "exportfs -r -a" was issued after /A and /B were mounted. When the client tried to mount (e.g., mount 192.168.20.143:/A/a /mnt/a), I get this error
mount.nfs: requested NFS version or transport protocol is not supported
This never happened before the power failure. This error persisted even after I completely removed and re-installed nfs-kernel-server and nfs-common in both the client and the server.
What makes things more confusing is that I have another linux server and a FreeNAS server running, and my client is able to mount NFS from both of them.
I have searched Google but I am unable to find the reason and unable restore nfs service from this server.
Please help. Thank you very much !!!
