I’m upgrading our Kong from 1.1.2 to 2.1.1 but while I can still make calls to Kong’s admin service successully, calls to our services are all providing no response with this in error.log

grant\_type=client\_credentials" while reading PROXY protocol, client: 127.0.0.1, server: 0.0.0.0:8080

We are using the oauth2 plugin.

Looking into this proxy protocol error I found that the nginx-kong.conf file being generated now shows

server {  
server\_name kong;  
listen 0.0.0.0:8080 proxy\_protocol;  
listen 0.0.0.0:8443 ssl proxy\_protocol;

Where it did not have the proxy\_protocol marker on those lines before.

Our config file has not changed and is:

trusted\_ips = 0.0.0.0/0  
admin\_listen = 0.0.0.0:8001  
proxy\_listen = 0.0.0.0:8080, 0.0.0.0:8443 ssl  
database = postgres  
pg\_host = 127.0.0.1  
pg\_port = 5432  
pg\_user = kong  
pg\_password = kong  
pg\_database = kong  
plugins = bundled,session
