DNS server communication failure (Response Code 503)

[gaankdoank]

Hi,

I've just install PDNS server & enable API with port 8081, then i've installed OperaDNSui and pointing API to the PDNS server API service in config.ini . When i accessing to OperaDNSui, it shown "DNS server communication failure" in http://my-url:8083/zones

I'm using it with docker. Where is my mistake or something else happen ?

In such cases, there are 2 places you should look:

1. The logs for your web server (ie. the DNSUI logs).
2. The logs for your PDNS server.

Usually the information found in those is enough to point to the source of the problem.
