Barcode Image not being displayed in the generated .pdf

[Hussein_Osseily]

Hello Everyon, 

I have a mini app that generate a label, it has been working for at least 6 month without any problems and without doin any changes to the backend / frontend, but suddenly today, the barcode that is of image type , is not being displayed in the generated label, instead , it looks like a broken link (image below) , when i click on it it redirects me to the image of the generated barcode which looks just fine. Any help would be appreciated.
Note: Previously generated labels.pdf open just fine .

link used as formula to generate the barcode: 
"https://barcode.tec-it.com/barcode.ashx?data=" &LEFT([MAWB],3)&RIGHT([MAWB],8)&"&code=Code128&translate-esc=on&dataattributekey_2=&dataattributeval_2=&dataattributekey_3=&dataattributeval_3=&dataattributekey_4=&dataattributeval_4=&dataattributekey_5=&dataattributeval_5=&digitallink=&imagetype=Jpg&eclevel=L&dmsize=Default"

I thought that it might be an issue with barcode.tec so i switched to webarcode, but i can still have the same issue.
Webarcode link that i am using as a formula: 
"https://www.webarcode.com/barcode/image.php?code="&LEFT([MAWB],3)&RIGHT([MAWB],8)&"&type=C128A&xres=2&height=130&width=358&font=5&output=jpeg&style=164"

links seems to be working perfectly but not the generated label, example below; 

The template is very straight forward: 

In view data i can see the generated barcode:
