I’ve contact my hosting support, they increase the PHP memory limit 4 times (to 2048M) , Also i’ve increase WordPress Memory Limit in wp-config.php but nothing changes.
The error still showing by Query Monitor:
GET https://api.redux.io/gfonts (cURL error 28: Failed to connect to api.redux.io port 443: Connection timed out).
I’m still waiting for some advice from you and Hosting Support to fix this.
