the reason is that the version of MiKTeX component in CTeX is too low , which cannot be connected to the server for update. Manual update will give an error message:

No Data:
Data: Get host by name failed in tcp_connect().

solution:
requires a higher version of MiKTeX to be installed. Download the latest version of the installation file from the website https://miktex.org/download. The installation path does not need to be in ctex. Packages that need to be installed can be installed directly in the console.

can also be automatically installed through a pop-up window during compilation in winedit10.3.
