Nginx - Upstream SSL - peer closed connection in SSL handshake

Question

I am getting this error:

Error frontend: 502 Bad gateway

99.110.244:443

2017/09/28 13:03:51 [error] 34080#34080: *1062 peer closed

Answer 1

Here is what worked for me. I had a server section with server_name setup with a wildcard search and had to do the following in the location section:

proxy_ssl_name $host;
proxy_ssl_server_name on;
proxy_pass https://istio-ingress-gateway

Answer 2

Adding this line after the proxy_pass worked for me.

proxy_ssl_server_name on;

Before that I did this from here

In REDHAT 7/ CentOS 7/ Oracle Linux 7: Install the certificate in your enviroment.

1. Download Active PEM certificate from: https://letsencrypt.org/certificates/ in /etc/pki/ca-trust/source/anchors
2. Execute: sudo update-ca-trust

Not sure if those last 2 steps needed, but doing both worked for me.

Cheers,

Answer 3

I had had this issue and I had to this to my location block

proxy_ssl_name your.proxiedserver.name; proxy_ssl_server_name on;

Answer 4

To improve the other answer I would say that

upstream is really important

For simple redirect from one domain into another just use this:

http {
....
upstream someserver {
        server your.domain.name.com:443;
}

location / {
   proxy_pass https://someserver;
}

}

Answer 5

Change your upstream to use the IP

upstream webshop_domain_be {
        server <IP>:443;
}

And then change your proxy_pass block to

location / {
   proxy_ssl_session_reuse off;
   proxy_ssl_server_name "webshop.domain.be";
   proxy_pass $scheme://webshop_domain_be;
}

If the above doesn't work then add proxy_ssl_server_name on; also to the config

Answer 6

i use this @nginx

ssl_session_cache shared:SSL:10m;
ssl_session_timeout 1h;
ssl_buffer_size 4k;

with

grep worker_processes /etc/nginx/nginx.conf
worker_processes auto; <<<-- auto not the default value "1"
