incorrect file reading in bash

Hi Experts.

I'm writing an automated Script in Bash, and I've got into a bit of a block...
I have a file called /scripts/resources/nodes,txt
The file currently hold only three lines:

10.5.17.3
10.5.17.4
10.5.17.5

and I have the following code:

#!/usr/bin/bash
filename="/scripts/resources/nginx_nodes_list.txt"
while read -r line
do
     NodeIP=$line
     echo "server $NodeIP {" >> /scripts/testloop.txt
done < "$filename"

However, when I run the scripts and cat the resulting file, I only see 2 lines:

server 10.5.17.3 {
server 10.5.17.4 {

meaning the scipt skips the last one, any idea why?
