Uploading file to Directus fails with 502 error

I can upload smaller (kilobytes) files like small images, etc. However trying to upload an mp3 that's around 5.2mb keeps failing with this error and these are my logs so far. I have added MAX_PAYLOAD_SIZE=50mb to my environment and deployed again to no avail. What am i missing? Thanks for the help in advance. PS: The errors in the log are from my attempts to delete partial uploads so any help with that will also be greatly appreciated
