Keep getting ‘failed to load resource… 524()’ error when trying to run import

I am trying to import a custom content type created with Pods. I have the Pods addon installed, and it works partially, but stops and errors out frequently. 

I am importing some regular fields and a gallery. At first I thought it was a cloudflare issue, pulling from their original website, but I moved the website to the same server, with no cloudflare, and it still doesnt work. I increased server timeout, website timeout, and increased max file size etc. and still the same errors: 

Failed to load resource: the server responded with a status of 524 ()

I uploaded the import file and the settings for the import.
