Can you check the permissions of Mount Point Directory??

Did you exported the FS using /etc/exports?
Can you post its content?
Are you touching with the same user on both hosts?

Type mount -v on both importers e compare output.

ithink the problem is only between two systems the nfs server and one of the other hosts, as I tried to mount exported nfs folder from the nfs server to the nfs client and the same problem still there.

is there any permission that can stops the writing on that nfs file system between these two systems.
