I am creating a NFS share. I've configured the NFS server and also the NFS client.
My share was working perfectly fine until yesterday and now I found out it doesn't work.
I redid all the steps of NFS configuration and it still doesn't work.
My problem is that when I try to access my mount folder using cat /mnt/nfs1.txt (which was working perfectly fine until yesterday), nothing appears on the screen. And it looks like it is hanged or it collapsed.
root@ela-native:~# cat /mnt/nfs1.txt
After this nothing appears on the screen and also I have to close the terminal to quit.
What am I doing wrong?
Edit1
The following are the steps in my configurations for the nfs:
NFS server:
sudo apt-get install nfs-kernel-server
sudo mkdir /var/nfs/general
sudo nano /etc/exports
/var/nfs/general *(rw,sync,no_root_squash,no_subtree_check)
sudo exportfs -a
sudo service nfs-kernel-server start
NFS client:
sudo apt-get install nfs-common
sudo mount 172.21.215.101:/var/nfs/general /mnt
And also if i run mount -t nfs, i get this:
root@ela-native:/home/salini# mount -t nfs
172.21.215.101:/var/nfs/general on /mnt type nfs (rw,vers=4,addr=172.21.215.101,clientaddr=192.168.164.78)
I also tried showmount -e 172.21.215.101 i got
clnt_create: RPC: Port mapper failure - Timed out
Edit2
And the i tried less /var/log/boot.log in the server machine and according to my understanding, i think that there is some error with the nfs server.
[ESC[0;1;31mFAILEDESC[0m] Failed to start Automatically refresh installed snaps.
[ESC[0;1;31mFAILEDESC[0m] Failed to mount /mnt/nfs/var/nfs.

What is the problem here?

I did sudo ufw status numbered and sudo netstat -nlp | grep :111. I got this:
root@wsm-ela-inc6:/home/test# sudo ufw status numbered

I tried again for showmount but then again the terminal give me this
clnt_create: RPC: Port mapper failure - Timed out
Also I tried sudo service portmap restart and i got portmap: unrecognized service. Also i tried sudo service statd restart, it went well. Then again i tried showmount but still the same problem.

I also tried netstat and got this:
