_From @rallep71 on Sun Sep 17 2017 16:15:42 GMT+0000 (UTC)_ Musste die host Datei noch bearbeiten…keine Ahnung warum… 127.0.0.1 localhost [85.214.xxx.xxx](http://85.214.xxx.xxx)[xxx.xxx.de](http://xxx.xxx.de) xxx ::1 localhost ip6-localhost ip6-loopback ff02::1 ip6-allnodes ff02::2 ip6-allrouters # Auto-generated hostname. Please do not remove this comment. [85.214.xxx.xxx](http://85.214.xxx.xxx) [xxx.stratoserver.net](http://xxx.stratoserver.net) xxxx danach geht es perfekt, Mercy 😉 Closed Issue ---

_From @hairmare on Mon Sep 18 2017 17:29:42 GMT+0000 (UTC)_ I’m not sure why you needed to hack your `/etc/hosts`. In most cases the URL used in airtime.conf should resolve properly using an external DNS. ---

_From @Robbt on Tue Sep 19 2017 20:51:05 GMT+0000 (UTC)_ Actually I think the lack of a /etc/hosts pointing to the local IP has caused my station some issues as well but mainly because we are using a OpenVPN connection to allow access to our server without modifying the firewall where our transmitter is located. Sometimes there are brief outages and because the DNS attempts to resolve to an external IP and then access itself via the OpenVPN IP it then causes issues with scheduling etc for Pypo. So for our libretime box located at our transmitter we have had to add the hostname pointing at 127.0.0.1 so that it will bypass any DNS resolution lookup failures. ---

_From @squiggleuk on Sat Oct 07 2017 17:42:06 GMT+0000 (UTC)_ I’m seeing a very similar issue on a LibreTime install that I started on today… - On air light is not red, but tracks show as playing to the left of it. - Icecast stream shows the offline metadata text - pypo log is showing HTTP 500 error on requests to ‘/api/register-component/format/json/api\_key/#############/component/pypo’ - airtime\_anaylzer.log is showing ‘[message\_listener] [ERROR] Connection to message queue failed’ and retrying every 5 sec. I’m not really sure where to start debugging this. OS is Ubuntu 16.04LTS. Checking my hosts file, I have ‘127.0.0.1 localhost servername’ so a ping to servername or localhost resolves to 127.0.0.1 Any help appreciated! ---

_From @squiggleuk on Sat Oct 07 2017 18:16:33 GMT+0000 (UTC)_ Typical, you spend ages trying to figure something out, eventually reach out for help, then figure it moments later!! It was the same issue with hosts file. I had 127.0.0.1 localhost servername What I needed was 127.0.0.1 locahost servername servername.domain.tld Clues about name resolution were in /var/log/airtime/pypo/notify.log for others ending up poking around here in future! ---

_From @Robbt on Sat Oct 07 2017 18:17:10 GMT+0000 (UTC)_ Hey SquiggleUK I commented out your API key because that shouldn’t be publically posted for security reasons. Glad you figured it out. ---

_From @squiggleuk on Sat Oct 07 2017 18:17:32 GMT+0000 (UTC)_ Ah, cheers for that 😉
