502 Sitemap Error

Hello!

I am receiving a 502 Error when I go to this certain sitemap: https://sellmynote.com/project-sitemap.xml

All of my other sitemaps, as well as sitemap index, works fine so not sure why this is happening.

I have also checked with my host, WP Engine, and this is their reply: “Generally 502s happen for 2 reasons on our platform- 1 there’s a break in the code, and 2 it’s hitting the max_execution_time that’s set to 60 seconds. I did check the error logs and don’t see it’s hitting the max execution time, and also don’t see any errors for it in the error logs. So, it’s hard to tell why it’s 502ing beyond something is wrong in the code.”

Please assist!
