Due to rapid growth of active installations, we got some heavy loads for CCSS online services. We just improved the server capability to better handle the requests. Now it should be fine. Please try more. If you still meet the null CCSS issue, please check your debug log and see what it says when fetching CCSS.
Hello! It’s still unable to generate using ccss.

Can you try it now? Thanks.
Hi,it’s back to the original issue now:
04/23/19 19:22:32.565 [:33052 1 apT] [CSS] saved ccss /usr/share/nginx/html/sample.rideelectricbikes.co.nz/wp-content/cache/ccss/product.css
04/23/19 19:22:32.565 [:33052 1 apT] [CSS] ccss con: /* null */
Just fixed a deployment issue. Do you mind to try it now?
Hello, it’s still the same. I checked the generated file and it only contains /* null */

04/24/19 11:56:51.727 [:43114 1 H8W] [CSS] ccss con: /*
null */
Are you able to see any clues on your server as to why it might be generating this way?
Hi @ivankyli, we found your site contain css error:
CssSyntaxError: /min/c2bf3.css:8:545292: Unknown word
could you please take a look at the CSS script, you can turn off CSS Minify for easier checking.
Hello, I’ve fixed the CSS issue but still getting empty response from ccss generation:

From my server I can wget https://as.wp.api.litespeedtech.com/ccss
Any other clues as to what’s happening?
Seems that your site is too large for generating CCSS within 15 sec, could you try to edit wp-content/plugins/litespeed-cache/admin/admin-api.class.php row 383:
From
$response = wp_remote_get( $url, array( 'timeout' => 15 ) ) ;
To
$response = wp_remote_get( $url, array( 'timeout' => 30 ) ) ;
for increasing the timeout?
Hello,
Thanks for the tip. Although I’m really surprised that would be the issue since my front page is only 546KB and fully loads within 2.0s according to gtmetrix..
What user agent does your server query with? Or any way to identify the request from server logs? Just want to make sure I’m receiving the request on the server.
Thanks,
Ivan.
Hi, just updating the issue. Increasing the timeout to 60s solves the issue. Is it possible to increase this timeout permanently in future releases of this plugin?
Thanks for your help,
Ivan.
