logged in user cache and open nodes as anonymous

We probably can’t help without more information only you have.

Have you modified the session cookie configuration?

@cilefen, no, it's the default configuration.

UPDATE: now another node has the same issue, and the basic page called "courses" that include these nodes has the same issue!

@cilefen, I'm ready to provide you with all the information you need to solve this issue.

@cilefen watch this video for more information: https://www.awesomescreenshot.com/video/29367897?key=5e76b806e3ed6f9df8e...

Are you using a CDN to cache HTML pages? If so does it definitely vary by session cookie?

Are you using Drupal's internal page_cache module?

Can you post the request and response headers from the anonymous version of the page when you visit it as an authenticated user?

Thanks a lot @catch.

I was using AdvAgg, but two days ago I disabled it, so, now I don't use any cache except the Drupal core caches.

yes, it's enabled by default "dynamic_page_cache" and "page_cache".

Please fond the Capture1, Capture2, and Capture3 for the request and response headers

There are CDN cache headers in the response.

@cilefen how can I fix it, the website is live! I need to solve it ASAP!

@yousefanbar if you configured the CDN, you need to check that, if your CDN is part of your hosting plan, you need to get in touch with them. Only you have this information, not us.

We can't troubleshoot particular websites quickly in this issue queue.
