 * For a few days my website suddenly displays the error **ERR_HTTP2_PROTOCOL_ERROR**
   in my browser window (see image).
 * This problem appears after a few minutes of use, when for example:
    - I deactivate a plugin,
    - save a modification from the back office,
    - modify a page via the ELEMENTOR plugin,
    - I am linking to the website while being logged in as an administrator.
 * This also happens when I’m in private browsing. After a few minutes, the error
   appears.
 * Here are several screenshots of the problem.

    - [error displayed](https://city-electronique.fr/wp-content/uploads/2022/06/erreur-2.jpg)
 * I translate the error screen below:
 * > This site is inaccessibleThe web page at [https://city-electronique.fr/wp-admin/nav-menus.php](https://city-electronique.fr/wp-admin/nav-menus.php)
   > may be temporarily inaccessible or may have been permanently moved to another
   > address website.
   >  ERR_HTTP2_PROTOCOL_ERROR
 * How can I solve my problem?
 * 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-after-using-few-minutes%2F%3Foutput_format%3Dmd&locale=en_US)

 * Talk to your web host about it, as the message is a hosting unavailability message.

   > Indeed, the latter has not been modified and does not encounter any disturbances.

 * I just purged the CDN to see if that changes anything.
