Title: ERR_HTTP2_PROTOCOL_ERROR Last modified: August 14, 2021 --- # ERR_HTTP2_PROTOCOL_ERROR * Resolved [richardbarnet](https://wordpress.org/support/users/richardbarnet/) * (@richardbarnet) * [4 years, 9 months ago](https://wordpress.org/support/topic/err_http2_protocol_error-7/) * After activating the JetPack plugin, I can no longer create new pages or posts, or edit existing ones. I now receive the following error message in Chrome (but also tested in FF and Edge): * This site can’t be reached The webpage at [https://bitcoininvestingbasics.com/wp-admin/post-new.php](https://bitcoininvestingbasics.com/wp-admin/post-new.php) might be temporarily down or it may have moved permanently to a new web address.** ERR_HTTP2_PROTOCOL_ERROR** * If I disable JetPack, everything goes back to normal functionality. I’ve looked through the settings and disabled mostly everything in JetPack, but the conflict still persists. I’ve disable ALL plugins and turned them back on one-by-one, and the only one that creates this issue is JetPack. * My current workaround is to deactivate JetPack when I need to create a new page or post or edit any content, then turn it back on afterward, but each time I have to go through the setup again, which is annoying. * Any pointers would be greatly appreciated. * WP Version 5.8 Active Theme: Divi, Version 4.9.11 Server architecture Linux 2.6.32-954.3.5.lve1.4.82.el6.x86_64 x86_64 Web server Apache PHP version 7.4.16( Supports 64bit values) * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Ferr_http2_protocol_error-7%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 9 replies - 1 through 9 (of 9 total) * Anonymous User 18700194 * (@anonymized-18700194) * [4 years, 9 months ago](https://wordpress.org/support/topic/err_http2_protocol_error-7/#post-14772470) * Hi [@richardbarnet](https://wordpress.org/support/users/richardbarnet/) – * Thanks for your thorough troubleshooting on this. Usually, this error happens when something is blocking access to the `xmlrpc.php` file that Jetpack uses to connect to your site. * At the moment, I am not seeing anything that is blocking your site. Could you kindly reinstall and reconnect Jetpack so that we can see if we have issues when your site is connected? * Additionally, it appears that you are using Cloudflare. Could you please try temporarily disabling Cloudflare to see if that makes a difference? * Let us know and we can take another look. * Thread Starter [richardbarnet](https://wordpress.org/support/users/richardbarnet/) * (@richardbarnet) * [4 years, 9 months ago](https://wordpress.org/support/topic/err_http2_protocol_error-7/#post-14773438) * Hi Bob, * I have reactivated and reconnect JetPack, and also paused CloudFlare. Issue still persists currently. * Thanks for the continued help. * Richard * Plugin Support [Animesh Gaurav (a11n)](https://wordpress.org/support/users/bizanimesh/) * (@bizanimesh) * [4 years, 9 months ago](https://wordpress.org/support/topic/err_http2_protocol_error-7/#post-14775813) * Hi Richard, * Currently, your login page is loading perfectly, and the same issue is not appearing in my browser. You can check here: [https://d.pr/i/P2XhfB](https://d.pr/i/P2XhfB) * Also, the Jetpack connection for your site is looking perfect. Could you please let us know if the issue is already resolved now? * Thread Starter [richardbarnet](https://wordpress.org/support/users/richardbarnet/) * (@richardbarnet) * [4 years, 9 months ago](https://wordpress.org/support/topic/err_http2_protocol_error-7/#post-14776522) * No, the issue still persists. The site works just fine, including the login page, until you click on “new” or “edit” both posts and/or pages. * There must be some WP settings that interfere with XML RPC, correct? I’ve tried re-enabling the Pingback and Trackback checkmarks, but that didn’t seem to help. Any other things I might try? * Richard * Anonymous User 18700194 * (@anonymized-18700194) * [4 years, 9 months ago](https://wordpress.org/support/topic/err_http2_protocol_error-7/#post-14776678) * Hi [@richardbarnet](https://wordpress.org/support/users/richardbarnet/) – * > There must be some WP settings that interfere with XML RPC, correct?

The connection that Jetpack uses is different than the pingback settings. * Could you give this a try with a default theme such as Twenty Twenty to see if it is a theme-specific issue? * Thread Starter [richardbarnet](https://wordpress.org/support/users/richardbarnet/) * (@richardbarnet) * [4 years, 9 months ago](https://wordpress.org/support/topic/err_http2_protocol_error-7/#post-14777253) * Oh, strange, it started working somehow. The only setting I toggled was “enable classic editor” in the Divi theme settings. I have no idea how these 2 things would conflict, but I’m glad it’s resolved now. * Thank you for your patience! * Richard * [Drosgrove](https://wordpress.org/support/users/drosgrove/) * (@drosgrove) * [4 years, 8 months ago](https://wordpress.org/support/topic/err_http2_protocol_error-7/#post-14852924) * Same problem. * But mine only occurs when I have WooCommerce and Jetpack activated. If I have both WooCommerce and Jetpack running, I can neither edit nor create a new posts because I get the exact same: * This site can’t be reached The webpage at [https://mysite.com/wp-admin/post-new.php](https://mysite.com/wp-admin/post-new.php) might be temporarily down or it may have moved permanently to a new web address.
