Mounting FSx for OpenZFS fails on Windows EC2 instance

Question

I am trying to set up shared storage using FSx for OpenZFS. Setting up filesystem went without problems, and I can mount it from Linux instances. However, mounting from Windows Server 2022 gives me Network Error 53.
* Client for NFS is installed
* I looked at security group for the ENI associated with the file system. It *didn't* have NFS inbound port (but Linux instances connected without problems). I added 2049 for anything in VPC - didn't make a difference.
* I tried from command line: 
```
mount \fs-0123.fsx.us-west-2.amazonaws.com\fsx\ Z:
```
 (that's how it shows in "Attach" screen); but also through Powershell and UI - no difference
* I tried IP instead of the DNS name - no difference.
* There is only one VPC; all route tables and subnets are quite straightforward.
I ran out of ideas... anything else could be the culprit?

Update: I solved the problem by adding other ports as described [here](https://docs.aws.amazon.com/fsx/latest/OpenZFSGuide/limit-access-security-groups.html):
111, 20001 and UDP
