stream_socket_client(): php_network_getaddresses: getaddrinfo failed: Name or service not known

RainLoop version, browser, OS: I'm using RainLoop 1.11.1 on a ubuntu 14.04 vps server. I installed the rainloop web client a few weeks ago and everything worked fine including receiving and sending mail, a few days ago when i try to login into rainloop mailbox i get stuck at the login screen with an error can't connect to server. I have tried checking my ports and permissions to no avail. Here is the screenshot of my imap and smtp configurations and the errors im getting.

Looks like your server is not able to resolv your domain. Can you ping your address? And can you connect to the server via terminal?

I'm getting this too on RainLoop community edition version 1.11.1, running on OpenBSD httpd + php-fpm v7.0.

Here is my config for this setup:

# pkg_add php php-fpm php-curl #-> choose version 7.0
# rcctl enable php70_fpm && rcctl start php70_fpm

# unzip rainloop-community-latest.zip -d /var/www/htdocs/rainloop

# chown -R www:www /var/www/htdocs/rainloop
# find /var/www/htdocs/rainloop -type d -exec chmod 755 {} \;
# find /var/www/htdocs/rainloop -type f -exec chmod 644 {} \;

# cat /etc/httpd.conf

types { include "/usr/share/misc/mime.types" }

server "comms.kousu.ca" {
        listen on * tls port 443
        tls certificate "/etc/letsencrypt/live/comms.kousu.ca/fullchain.pem"
        tls key "/etc/letsencrypt/live/comms.kousu.ca/privkey.pem"
        directory index "index.php"
        root "/htdocs/rainloop/"
        location "*.php" {
            fastcgi socket "/var/www/run/php-fpm.sock"
        }
        location "/data*" {
            block
        }

        log syslog
}

# force https
server "comms.kousu.ca" {
        listen on * port 80
        block return 301 "https://$HTTP_HOST$REQUEST_URI"
}

I get it with any domain; even, for example, imap.gmail.com. If I, use 127.0.0.1 or my server's public IP the test passes (but then trying to log in doesn't work because I have dovecot running SSL and only SSL, which means rainloop needs to know its proper domain name).

I tried taking rainloop out of chroot and it fixed it; perhaps your server is choorted, @gathagu354?

My non-chrooted setup looks like:

# cat /etc/httpd.conf

types { include "/usr/share/misc/mime.types" }

chroot "/"

server "comms.kousu.ca" {
        listen on * tls port 443
        tls certificate "/etc/letsencrypt/live/comms.kousu.ca/fullchain.pem"
        tls key "/etc/letsencrypt/live/comms.kousu.ca/privkey.pem"
        directory index "index.php"
        root "/var/www/htdocs/rainloop/"
        location "*.php" {
            fastcgi socket "/var/www/run/php-fpm.sock"
        }
        location "/data*" {
            block
        }

        log syslog
}

# force https
server "comms.kousu.ca" {
        listen on * port 80
        block return 301 "https://$HTTP_HOST$REQUEST_URI"
}

# mkdir /logs  # because httpd(8) is hardcoded to use this path, assuming it will be under the chroot

and also patch /etc/php-fpm.conf:

-chroot = /var/www
+chroot = /

and rcctl restart php-fpm.

If I figure out how to get rainloop chroot'd I will post it here.

[kousu]

I figured it out!

Not having DNS inside a chroot is a reasonably common problem, and the fix is to make sure resolv.conf exists in the chroot:

# mkdir /var/www/etc/                                                                                                                                                    
# cp /etc/resolv.conf /var/www/etc/        

After this the IMAP tester works.

[kousu]

But mind, if your setup was working, then you must not have been in a chroot in the first place, probably. But maybe /etc/resolv.conf got corrupted or something?

[kousu]

And for future reference, you probably also want

# cp -r /etc/ssl /var/www/etc

so you can enable cert verification.

@akmet pinging my server works fine and my dns seems to be functional

@kousu My setup was working on the first installation but later everything just stopped.I havent installed anything else to my vps since i installed rainloop. Do you mind explaining how i chroot in the first place?i'm a newbie to ubuntu administration.:-)
