Hi everyone,

Since a few days, my Selfoss installation is unable to update feeds.
I get the following error message for every entry in my source list :

```
2017-02-23 10:22:11error loading feed content: fsockopen error: php_network_getaddresses: getaddrinfo failed: Name or service not known
```

(It is in red, right under the source parameters, and the whole thing is circled is red.)

Everything was working fine since my first installation a few month ago.
I use a VPS with Debian 8.

Some research on google told me that this error message may be related to host configuration,
and I think I got a debian update that modified the host file around the same date the
issue occurred (I am not 100% sure, I didn't pay a lot of attention to the update as I didn't think it could mess with any of my services).

Anyone know how to fix it ?

Thank you for reading,
Nephe
