I followed this and this tutorial to create and mount fsx.
Sadly the command I run, e.g. mount -t nfs -o nfsvers=4.1 fs-<someid>.fsx.us-west-2.amazonaws.com:/fsx/ /fsx
, gets stuck and won't end (unless I define a timeout in the command and then it reaches it).
(I also tried for example mount -t nfs -o nfsvers=4.1 fs-<someid>.fsx.us-west-2.amazonaws.com:/ /fsx
I tried going to the VPC as suggested by other SO posts and in the inbound rules allowed all tcp and udp ports. Sadly nothing worked.
I think that maybe it has something to do with the routing table but I really don't have much knowledge in this.
