    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.

    I translate the error screen below:

    This site is inaccessibleThe web page at 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?

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

    Thank you for your answer, the hosting has answered this :

    After verification, it is not an error related to our server in your case. Indeed, the latter has not been modified and does not encounter any disturbances.
    This is a common error that can have several causes, here is an external link about it: https:

    Right now, you can try the following actions:
    – temporarily deactivate the CDN,
    – check your scripts and modules in place.

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