mount.nfs: mount(2): Permission denied in Ubuntu 20.04 server & client

I strictly followed the instructions but while executing mount command got the following.

root@cgs1:~# mount -vvvv cgs2:/2d1 /mnt
mount.nfs: timeout set for Thu Aug 20 23:12:54 2020
mount.nfs: trying text-based options 'vers=4.2,addr=,clientaddr='
mount.nfs: mount(2): Permission denied
mount.nfs: access denied by server while mounting cgs2:/2d1

I have checked my /etc/exports, ufw status etc but failed to solve it.

My point is please add troubleshooting in this article.

The error you are receiving means that the NFS server doesn’t have the correct permissions to allow this client to connect.

You would need to include your config file and show what host access you have setup on the server side to ensure that you have the correct IP address and directories setup for exporting.
