bash sh script with user permissions 755, cannot be run

Why can't run it?
If I run it in the following way, it works:

[usuario@MyPC ~]$ sh ./x11vnc.sh
PORT=5900

First, the permissions, so that you can see that it is in 755.

ls -l
-rw-rw-rw- 1 usuario users  4485 dic  2 11:35  x11vnc.log
-rwxr-xr-x 1 usuario users   117 nov  7 14:06  x11vnc.sh

Second,the script file

cat x11vnc.sh
#!/bin/bash
x11vnc -nap -wait 30 -noxdamage -passwd somepass -display :0 -forever -o ~/x11vnc.log -bg -rfbport 5900

Third, I must clarify the structure of the disks

lsblk 
NAME        MAJ:MIN RM   SIZE RO TYPE  MOUNTPOINTS
sda           8:0    0   3,6T  0 disk  
├─md126       9:126  0   3,6T  0 raid1 
│ ├─md126p1 259:3    0   3,6T  0 part  /home/usuario
│ └─md126p2 259:4    0     8G  0 part  [SWAP]
└─md127       9:127  0     0B  0 md    
sdb           8:16   0   3,6T  0 disk  
├─md126       9:126  0   3,6T  0 raid1 
│ ├─md126p1 259:3    0   3,6T  0 part  /home/usuario
│ └─md126p2 259:4    0     8G  0 part  [SWAP]
└─md127       9:127  0     0B  0 md    
nvme0n1     259:0    0 232,9G  0 disk  
├─nvme0n1p1 259:1    0 232,6G  0 part  /
└─nvme0n1p2 259:2    0   256M  0 part  /boot

I am the user usuario. I can edit and modify the x11vnc.sh file as I wish, but I can't run it, and I need to run it to include in the auto-start session of the plasma.

[usuario@MyPC ~]$ ~/x11vnc.sh
-bash: /home/usuario/x11vnc.sh: permission denied

Thank you all, specially to @CharlesDuffy

I change the fstab line from

UUID=16b711b6-789f-4c27-9d6c-d0f744407f00 /home/usuario ext4 auto,exec,rw,user,relatime 0 2

to

UUID=16b711b6-789f-4c27-9d6c-d0f744407f00 /home/usuario ext4 auto,rw,user,exec,relatime 0 2

The position of exec is important, since user also applies noexec. By putting exec after user, you ensure that exec is set. The most important options should be listed last
