I noted suggestions in post link below, but makes no difference. The critical css generation worked in the past. My url above https://wordpress.org/support/topic/unable-to-optimize-critical-css-loading/#post-17741108
Hi @pkrynauw –
Looking at your site, we are seeing the message: ERROR: cURL error 28: Operation timed out after 5002 milliseconds with 0 bytes received This error generally indicates that your web server may be overloaded and may be exceeding its resource limits. This will prevent the Critical CSS from being generated as it will impact our ability to communicate with your website.
Please reach out to your hosting provider to check the load on your server. If they confirm that it looks good, please ask them to add our IPs to their allowlist. This will make sure that we aren’t being blocked.
Let us know how it goes.
I referred your suggestion to my hosting supplier. They tested and increased limits. Unfortunately it does not make a difference. Please advise
My hosting supplier made the following changes, but it does not solve the problem:
Pcre.backtrack_limit = 10000000
Pcre.recursion_limit = 10000000
Second change:
upload_max_filesize = 500M
post_max_size = 80M
max_execution_time = 500
max_input_time = 500
max_input_vars = 2000
memory_limit = 512M
Please assist with next steps
Thanks for sending those over. We’re checking with our developers about suggested next steps; we’ll get back to you soon!
Hi @pkrynauw,
Good news! The Jetpack connection issue on your site has been resolved. I can see that the Critical CSS generator is also working, with the last generation occurring a day ago. Everything appears to be functioning correctly on our end. Could you please confirm this on your side?
While we’re in touch, I wanted to bring something else to your attention. We noticed a timeout issue with the REST API on your site. This could potentially cause performance issues. To address this, I recommend reaching out to your hosting provider and asking them to investigate the timeout issue. They should be able to assist you in resolving this.
Please let us know if you need any further assistance.
