nfs client find server but does'nt export directory

I have updated my NFS server but putting sata raid inside.

after ré installing 12.1 opensuse , the stations (two) can’t export directory from nfs server.

in yast if i open windows choice for directory nothing appear, if i write directory i got an “internal error”

I have put name of the server instead IP adresse , that’s not solved the problem

??

The problem is solved. i re create export directory with yast on the server and each stations can mount nfs remote directory
great !
