Gitlab code review submit button and comments display not working

I’m trying to learn how to work with gitlab’s devops and i come across the following issues:

  1. during the comments overview the gitlab takes a really long time to load and when it finally finishes’ a red banner with something went wrong while trying to fetch the comments. Please try again". and nothing is logged to production.log file.
  2. when i press the button to submit a code review and not submit individual comments it also takes a ton of time and fails. Here also nothing is logged to try and understand the problem was.

my question is where/what to do to either try to solve this or to at least find out whats causing the problem ?

would love some help on the matter because it’s a really weird problem
