    Hi everyone, I encountered difficulties in mine website.

    In this Monday, I try to check update info on WordPress wp-admin page.

    Since Ive checked that, I get cURL error 28 with three functions as follow:
    1. wp_version_ckeck()
    2. wp_check_browser_version()
    3. wp_check_php_version()
    Each function will cause high time cost, even time out(http code:504).

    Now I is difficultyly enter each wp-admin page, ex. pluging page态edit post page …etc

    Is there anyone know reason?

    BTW front-end page is work normally.
