A 404 error is an indication that the client has reached the application and it has said "the thing you asked for isn't here" - it's a "Not Found" error.
What this means is that your application is running and it is responding but what the client is asking for can't be delivered - this could be because the client has asked for the wrong thing; or the server component has some fault where it isn't returning or finding the correct "thing" to respond with.
You don't say whether the load balancer is doing anything else - if you're using ALB and (maybe) have WAF enabled then I would check to see that the WAF rules aren't going to deny traffic at particular times; or have dependencies that will cause them to fail. However, in the simplest case (where the load balancer is just being used to distribute traffic) then that won't be the case.
I'd also recommend enabling access logs to try and debug the issue.
After all this, if you definitely think it is a load balancer fault then please create a support case - the support team can look at the dates and times and see if there was any issue with the load balancer itself.
