This is my nginx setup. And alsoI use Docker and Docker-Compose to run my nginx and webservice

This is what I see when I run `nginx -V` inside the docker

nginx version: nginx/1.15.5
built by gcc 6.4.0 (Alpine 6.4.0)
built with OpenSSL 1.0.2p 14 Aug 2018
TLS SNI support enabled

    return       444;
}

```

but for some reason, the cert that's being retrieved is always the one for domain\_1 even when i visited domain\_2.

I am not sure where I went wrong.

domain\_1 is working well
