CF error 520 is keep coming intermittently on our domains

Hello Garret and thank you for the quick response.

Our domain is navlungo.com. On Monday this week we noticed that only some of our users have the attached error when they try accessing our homepage.

Today between 11:52-15:00 GMT +3 we had a different issue where some of our users were not able to load our website(no errors, just not loading the page) and some of our users seeing a 524 error.(screenshots attached)

We are sure that nothing is wrong in the application since the issue disaapeared when we toggled off the Cloudflare proxy option in our dns addresses and used amazon’s cloudfront for cdn instead of Cloudflare.

We appreciate any help.

Thanks
