Title: Automatically set preconnect hints issue Last modified: June 7, 2020 --- # Automatically set preconnect hints issue * Resolved [Vladi](https://wordpress.org/support/users/loveinlions/) * (@loveinlions) * [5 years, 11 months ago](https://wordpress.org/support/topic/automatically-set-preconnect-hints-issue/) * Hi Sam, * I am using PHP 7.3 WordPress 5.4.1 and I have tried deactivating all plugins but auto-feature of the Pre Party does not work. I have tried to reset and reload the website multiple times but the hints page stays blank. Have you heard about similar issue from other users? And if yes, what could be the reason?

I have a few questions: -Are you able to add hints manually? ( I have heard of this issue). If so can you also edit and delete them properly?- Has the auto preconnect feature always worked for you in the past? * For the short term I suggest using version 1.7.1: [https://downloads.wordpress.org/plugin/pre-party-browser-hints.1.7.1.zip](https://downloads.wordpress.org/plugin/pre-party-browser-hints.1.7.1.zip) * Thread Starter [Vladi](https://wordpress.org/support/users/loveinlions/) * (@loveinlions) * [5 years, 11 months ago](https://wordpress.org/support/topic/automatically-set-preconnect-hints-issue/#post-12951079) * [@samperrow](https://wordpress.org/support/users/samperrow/) thank you for replying on Sunday. * – I am able to add hints manually but further testing with webpagetest shows that none of those hints influence the domains. For example, I added [https://stats.g.doubleclick.net](https://stats.g.doubleclick.net) as per your example but nothing changed in the test: [https://prnt.sc/svgs95](https://prnt.sc/svgs95) – It was a fresh install for me, so the auto preconnect feature did not work straight away. – I’ve just tried 1.7.1 but the auto feature does not work either. * Any thoughts? * Plugin Author [Sam Perrow](https://wordpress.org/support/users/samperrow/) * (@samperrow) * [5 years, 11 months ago](https://wordpress.org/support/topic/automatically-set-preconnect-hints-issue/#post-12951095) * [@loveinlions](https://wordpress.org/support/users/loveinlions/) Is your site using any caching system or CDN? Can you tell me your site’s domain? * Thread Starter [Vladi](https://wordpress.org/support/users/loveinlions/) * (@loveinlions) * [5 years, 11 months ago](https://wordpress.org/support/topic/automatically-set-preconnect-hints-issue/#post-12951128) * Yes, sure: [helenarecipes.com](https://www.helenarecipes.com) * – CDN: no CDN is being used now. I used to have Cloudflare but no more. – Cache: I am using [Cache for WordPress Performance ](https://wordpress.org/plugins/cache-performance/) plugin but deactivating it and clearing cache does not help. It’s currently active but please let me know if you’d like me to deactivate it for testing. * Plugin Author [Sam Perrow](https://wordpress.org/support/users/samperrow/) * (@samperrow) * [5 years, 11 months ago](https://wordpress.org/support/topic/automatically-set-preconnect-hints-issue/#post-12951134) * [@loveinlions](https://wordpress.org/support/users/loveinlions/) -Do you have the “Automatically set preconnect hints” option to “yes”? -Can you click the “ Reset” button to the right of “Reset automatically created preconnect hints”? Both of these options are in the “settings” tab. * The auto-preconnect hint feature is supposed to work by running a script, collecting the needed info, create hints from that, and not run again unless the user specifies. * Thread Starter [Vladi](https://wordpress.org/support/users/loveinlions/) * (@loveinlions) * [5 years, 11 months ago](https://wordpress.org/support/topic/automatically-set-preconnect-hints-issue/#post-12951161) * [@samperrow](https://wordpress.org/support/users/samperrow/) – Yes: [https://prnt.sc/svhcvt](https://prnt.sc/svhcvt)– Done. Reloaded the live page, too. No changes. * Plugin Author [Sam Perrow](https://wordpress.org/support/users/samperrow/) * (@samperrow) * [5 years, 11 months ago](https://wordpress.org/support/topic/automatically-set-preconnect-hints-issue/#post-12951198) * [@loveinlions](https://wordpress.org/support/users/loveinlions/) Looks like Autooptimize has compressed the JS file needed to acquire the preconnect hints ([https://www.helenarecipes.com/wp-content/cache/autoptimize/js/autoptimize_single_991159460a232e753aae9874b5ee8356.js](https://www.helenarecipes.com/wp-content/cache/autoptimize/js/autoptimize_single_991159460a232e753aae9874b5ee8356.js)). * Because the plugin script has been cached, (and thus set to be fired every page load) I have had to put in a check to prevent my script from sending the hints every page load. * I got the script to fire correctly on your site- you should have hints created for translate.google.com, translate.googleapis.com, fonts.googleapis.com, fonts. gstatic, gstatic, googletagmanager, and google-analytics. * I believe there’s an option in Autooptimize that allows you to ignore certain JS files, if so please tell it to ignore “find-external-domains.js” from my plugin. * Plugin Author [Sam Perrow](https://wordpress.org/support/users/samperrow/) * (@samperrow) * [5 years, 11 months ago](https://wordpress.org/support/topic/automatically-set-preconnect-hints-issue/#post-12951203) * You will need to clear your front end cache to allow those new hints to be displayed. * Thread Starter [Vladi](https://wordpress.org/support/users/loveinlions/) * (@loveinlions) * [5 years, 11 months ago](https://wordpress.org/support/topic/automatically-set-preconnect-hints-issue/#post-12951308) * [@samperrow](https://wordpress.org/support/users/samperrow/) Thank you for looking into my website and the detailed explanation. * As per your instructions, I have added the script to the exclusions: [https://prnt.sc/svi4cp](https://prnt.sc/svi4cp), cleared cache multiple times (both front-end and back-end), then clicked “reset” and reloaded the page. Repeated the same steps over and over again, but nothing changes, the hints are still empty: [https://prnt.sc/svi5ey](https://prnt.sc/svi5ey) * In fact, I have even tried deactivating Autopimize and other plugins, still nothing. * Plugin Author [Sam Perrow](https://wordpress.org/support/users/samperrow/) * (@samperrow) * [5 years, 11 months ago](https://wordpress.org/support/topic/automatically-set-preconnect-hints-issue/#post-12951332) * Try to uncheck the “Aggregate all linked Js-files…” box, and change the link to my plugin script to “wp-content/plugins/pre-party-browser-hints/js/find-external- domains.js”. * I just tried it on my machine and it worked. * Thread Starter [Vladi](https://wordpress.org/support/users/loveinlions/) * (@loveinlions) * [5 years, 11 months ago](https://wordpress.org/support/topic/automatically-set-preconnect-hints-issue/#post-12951364) * [@samperrow](https://wordpress.org/support/users/samperrow/) Nope, still nothing: [https://prnt.sc/svihsx](https://prnt.sc/svihsx) I have also tried unticking the following: [https://prnt.sc/svii5r](https://prnt.sc/svii5r) but it didn’t help either. 😱 If it works on your side but doesn’t on mine, could it be something server-side that is in the way? * Plugin Author [Sam Perrow](https://wordpress.org/support/users/samperrow/) * (@samperrow) * [5 years, 11 months ago](https://wordpress.org/support/topic/automatically-set-preconnect-hints-issue/#post-12951383) * Can you try again, this time with your performance cache plugin deactivated? * Thread Starter [Vladi](https://wordpress.org/support/users/loveinlions/) * (@loveinlions) * [5 years, 11 months ago](https://wordpress.org/support/topic/automatically-set-preconnect-hints-issue/#post-12951388) * Deactivated: [https://prnt.sc/svip26](https://prnt.sc/svip26) but no changes… * Thread Starter [Vladi](https://wordpress.org/support/users/loveinlions/) * (@loveinlions) * [5 years, 11 months ago](https://wordpress.org/support/topic/automatically-set-preconnect-hints-issue/#post-12951526) * I think I will need to spend some time working through all plugins to find the one that blocks yours. If it works on your side there’s got to be something on mine that prevents your script from working, even though we’ve tried to eliminate those that could really affect it. Either way, I appreciate your willingless to help and for taking time to trying to find what’s wrong. 5 stars for your support from me. Thank you!
