send() failed (111: Connection refused) while resolving, resolver: 127.0.0.1:53

Question

Because of SSL stalping errors I had to set

ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_ciphers 'EECDH+AESGCM:EDH+AESGCM:AES256+EECDH:AES256+EDH';
ssl_prefer_server_ciphers on;
ssl_stapling on;
resolver 127.0.0.1;
ssl_stapling_verify on;

But since then I’ve been hit with this error

send() failed (111: Connection refused) while resolving, resolver: 127.0.0.1:53

How do I resolve this?

Solution

Hi

Had a same fresh error in my nginx error.log

2019/04/16 14:18:49 [error] 16988#0: send() failed (111: Connection refused) while resolving, resolver: 127.0.0.1:53

For me helped below Check first your DNS Nameservers.

My example is for dns resolver godaddy. with:

ns47.domaincontrol.com

ns48.domaincontrol.com

Make an nslookup for these domains and you will get two IP-s. Update your /etc/resolv.conf with given nslookup in domain:

• search domaincontrol.com
• nameserver 97.74.103.24
• nameserver 173.201.71.24

Save file, restart nginx and wait few sec. My error message dissapeared from logs. Hope it helps.

Use the correct IP address of your nameserver.

On AWS, the problem was resolved when I added the nameserver available in /etc/resolv.conf as the first priority (leaving the previously added 8.8.x.x Google nameservers as secondary/tertiary fallbacks)
