DNS Problem, Servers Default Page Shows Up For Some Visitors

[guiman]

Hello,

I have this issue only for one of my domains:

Some visitors see the Plesk default server page and not the regular homepage. The name of the domain is "silbertreu . de".

For example, GTmetrix is browsing the Plesk default server page but most of the visitors see regular homepage which is in httpdocs. I tried with or without the Plesk DNS server, it makes no difference. The domain has 3 subdomains which have the same issue.

Can anybody help please?

Hi guiman,

please open http://144. 76. 155. 212 ( the assigned IP for "silbertreu . de" ). As you can see, the default content from Plesk is being delivered.
Such issues appear, if you leave the default apache and/or nginx settings to its standard configuration(s), where the standard server-ip is defined to deliver content from "/var/www/vhosts/default/htdocs". Please check for existing "default.conf" and "default-ssl.conf" - files at "sites-enabled" in your apache and/or nginx folders, located under "/etc/" ( these files might as well being named "000-default.conf" or/and "000-default-ssl.conf"). You might delete the symlinks, to avoid such issues, after you setup your first domain for the main server-ip.



Please consider as well you have a look at:

https://www.ssllabs.com/ssltest/ana...s=2a01:4f8:200:23d3:0:0:0:2&ignoreMismatch=on

... and search the Odin knowledge base and the forum with the keyword "poodle", please, to find resolutions, as for example:

Poodle:

[Plesk] CVE-2014-3566: POODLE attack exploiting SSL 3.0 fallback ( KB - article: 123 160 )​

In some cases you might experience issues with incompatibilities for some browser and/or eMail - clients, after you followed the KB - article 123 160. It might help to read:

SSL POODLE / SSLv3 bug ( Odin / Parallels Forum - Link )​

... to solve such issues, because there are several additional solutions provided in this thread.

Hi UFHH01,

thank You for Your help and the poodle advice. I need further assitance please:

I am running Centos 6.5 with Plesk 12 and the only file I can find on the server which is matching somehow is:

/etc/httpd/conf/plesk.conf.d/server.conf

In this file the document root is set to /var/www/vhosts/default/htdocs on 9 different lines. (General, Virtual Host, Virtual Host SSL, Virtual Host ipv6, Virtual Host ipv6 SSL)

What exactly do I have to change? I dont understand your instruction regarding the "symlinks". There is no file with a name like default.conf in the etc-folder. Can I edit server.conf-file in the Plesk GUI as well?


Greetings from Munich

Hi guiman,

actually, it would be sufficient to define a "standart" domain for an IP. Such settings are done over "Home > Tools & Settings > IP Addresses". Check again "http://144. 76. 155. 212" after your changes and generate the templates manually, in case it hasn't been done by Plesk:

/usr/local/psa/admin/sbin/httpdmng --reconfigure-all​

If you manually change configuration files, which are generated out of templates, then you might experience issues/problems in case of updates/upgrades/patches and as well, each time the generating process is necessary in case of hosting / webserver changes. Please keep an eye on the informations on the top of such files:

#ATTENTION!

Thank You, that fixed it, reconfiguration was done by Plesk!
