Why do I get a 502 error? Under what circumstances would I get a 502 code sandwiched between multiple 304 codes?

    304 is for a css file and the 502 is for a js file. Have you review if you can access both of those files in each of servers individually that the ALB is pointing towards?

    Also, Why are the urls different? On includes port 443 and the other doesn't.
