nfs share accessible from one computer but access denied from another one [closed]

I set up a nfs share on my raspberry pi following this : My /etc/exports looks like this :

pi@nextcloudpi:~ $ cat /etc/exports
/export 192.168.1.0/24(rw,fsid=0,insecure,no_subtree_check,async)
/export/users 192.168.1.0/24(rw,nohide,insecure,no_subtree_check,async)

I mounted it on my desktop (ubuntu 20.04) without any problem using this :

sudo mount -t nfs -o proto=tcp,port=2049 192.168.1.48:/ /mnt

Problem is, when I try to mount it on my laptop, which has pretty much the exact same ubuntu as my desktop, i get an error :

laptop:~$ sudo mount -t nfs -vvvv -o proto=tcp,port=2048 192.168.1.48:/ /mnt
mount.nfs: timeout set for Thu Feb 25 18:22:35 2021

mount.nfs: mount(2): Permission denied
mount.nfs: access denied by server while mounting 192.168.1.48:/

They're both on the same network. The only difference I can think of is that my laptop is Wi-fi connected while my desktop is ethernet plugged in. Anyone knows what might be the problem ?

So turns out a good night's sleep helps out a lot. If you look closely, I was using port=2049 on the desktop, and port=2048 on the laptop. Correcting the typo was enough to fix it.
