Phone and tablet - Page reloads due to a problem occuring

If I am on phone or tablet and I stay on a drama series page longer to read further comments, the page reloads due to an error. The page also becomes slow and unresponsive before reloading.

 Ji-N:

I believe that may be due to the long comments thread and your device was unable to handle it. Does it happen on every page or just a specific one?

Happens mainly to pages where there are more comments and I need to scroll a bit further. It happened a few times in the past when I was on my laptop but with laptop now it seems the issue is fixed.
