A 403 Forbidden error of this nature usually occurs when a Web-Application Firewall is associated with the Application Load Balancer. If that is the case, we would recommend reviewing your WAF logs to see if any of your custom rules have blocked the requests. 

Good to note that classic WAFs (newer version released 2020) only store logs from the past 3 hours. So if your request was before that window, generate the request again, wait for a few minutes and identify which WAF rule is blocking your request in the logs. Once that is identified, a custom String/Regex Match Pattern can be created for that request to whitelist it as a legitimate one. 

More info on WAF can be found here -  https://aws.amazon.com/waf/getting-started/
