Wp import error

I am encoutering an error while importing using WP IMPORT PLUGIN.
The error says : Import Error{“code”:“internal_server_error”,“message”:"
The below is also says : Your server terminated the import process
Ask your host to check your server’s error log. They will be able to determine why your server is terminating the import process.

Please can someone assist me on this issue.

You need to ask your host. Cloudflare is not your host.
