TLSv1.3 TLS_AES_128_GCM_SHA256 Error

Hello,
I don't think your nginx is the problem, we have the same error, we have enabled TLSv1.3 support in apache, however it continues with the same problem "502" detail:

We think we should enable TLSv1.3 on the Elastic Load Balancer, but we know how to do it.
