NFS - After an uptade clients can't mount exported directories

After an update on muy NFS server, clients can't mount exported directories. I didn't chage the configuration or any thing...
I readed other related therads but I can't find an explanation. Some one can help me, please? I'm desperated... :'-(

$ sudo mount -vvv -t nfs4 -o sec=krb5,rsize=8192,wsize=8192,timeo=14,_netdev servername:/dir /mnt/nfs

mount.nfs4: timeout set for Tue Nov 20 20:03:02 2018
mount.nfs4: trying text-based options 'sec=krb5,rsize=8192,wsize=8192,timeo=14,addr=192.168.1.134,clientaddr=192.168.1.128'
...
...
And it stay there blocked for ever...

$ showmount -e servername
