Storage gateway Mount on RHEL fails

Hi Team... We installed a On Account 1 Storage Gateway , Linked with S3 Bucket to it On Account 2 We are able to Mount this NFS - on Oracle Linux Server release 7.8 --> mount works fine --> and we are able to see the new mount as well

[oracle@rdkpri1 ~]$ df -h Filesystem Size Used Avail Use% Mounted on 18.232.188.134:/oracle-harish-gateway-int 8.0E 0 8.0E 0% /mnt <<------ Stg GWY --> works fine

################## When we mount this same Gateway on a RHEL machine on Account 2 --> it fails
