1. An error occurred while updating Hueman Addons: Download failed. cURL error 18: transfer closed with 2183267 bytes remaining to read. See Figure 1.
2. Reference URL: https://www.shuijingwanwq.com/2021/02/19/4734/ . The solution was to download it on the server and place it in the plugin directory. I planned to fundamentally resolve this issue later when I had more time, or during the next Hueman Addons upgrade, to enable automatic updates in the backend.
3. Checked the server’s Nginx logs. See Figure 2.

4. After deleting the Hueman Addons plugin from the WordPress backend, I reinstalled Hueman Addons. The same error was still reported. See Figure 3.
5. Reference URL: https://www.admincolumns.com/forums/topic/plugin-does-not-update-anymore/ . It suggests trying the installation or update multiple times, which will eventually succeed. On the 4th attempt, the installation succeeded. Note: Before installing, I had already disabled the plugin: Kill 429. I am not sure if there is a connection between the two. Checked the Nginx logs. See Figure 4.

6. Checked the plugin directory: /data/wwwroot/www.shuijingwanwq.com/wp-content/plugins, and the directory hueman-addons exists there. See Figure 5.
