No output / not showing the source from the page

I am trying to scrape specific result from this website : https://quotes.wsj.com/PH/DFNN and put it on a widget on our WordPress Page (running on CentOS webserver)

Problem is,the output is not showing on a “TEST”,
(SCREENSHOTS)

https://prntscr.com/6683w9
https://prntscr.com/66846o

Shortcode : [wpws url=”https://quotes.wsj.com/PH/DFNN” query=”#quote_val” ]

Template tag : <?php echo wpws_get_content(‘https://quotes.wsj.com/PH/DFNN&#8217;, ‘#quote_val’ ); ?> (where to put this?)

This is the website I’ve been working on : 124.83.11.80

I’ts been a week of troubleshooting/googling this problem,so i tried posting it here,expecting somebody had this same problem before.

*I Tried deactivating all other plugins, aside from Web scrapper (still no output.)
* All plugins are updated
* Tried changing the ‘Time out’ from 2 to 30 (yep,2,3,4 up to 30,just to test everything)
* I also gave 777 permission to wordpress/wp-content/x/x folders and subfolders,
* My webserver can ping the source,so i think there’s no problem with the nerwork settings.
/nslookup (working)
* I have the minimum requirements & dependencies.
* Turned off the firewalls

*We try to put it on a hosting site temporarily (bluehost) and IT IS WORKING*. check it out at https://www.dfnn.biz I don’t know why it is not working on my Webserver.

Any other advice or suggestions regarding this matter will be very helpful for me.

Thanks.
