Thank you for the screenshots. Here are some questions which should help in further troubleshooting:
1. Are the products included in the campaign published, on stock and publicly accessible by all customers?
2. Isn’t the access to these products restricted e.g. only for logged-in users?
3. Do you have any rewrite rules added in the .htaccess file, do you use any plugins applying the SSL or the ones which might have an influence on URLs structure?
4. Have you tried to temporarily disable the minification and code optimization plugins in order to exclude they may interfere here?
Kind regards,
Luke
