  • The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.
  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.

DonDDD

New Pleskian
All of a sudden I'm getting this in my error logs a lot on one particular domain (also has SSL).
None of my other sites are having this problem.

When trying to load the site in the browser I get
"504 Gateway Time-out"

Any insights on this?
 
Hi DonDDD,

pls. make sure, that your webserver is active and running and make sure that your depending php-fpm - service ( if in use for your domain! ) is active and running as well.


Code:
service apache2 status
( service httpd status )

service nginx status

service php5-fpm status
( service plesk-phpXX-fpm status )

... or/and check the status over the Plesk Control Panel:

=> HOME > Tools & Settings > Services Management
 
Thanks for the reply, next time it starts this problem I'll check.

However, I have 15 other domains on the server, all working perfectly fine (Apache, Nginx) while I get this error on just one of the domains. When I restart the server the error goes away.

That's why I'm confused...
 
Hi DonDDD,

pls. note as well that PHP - issues/errors/problems and poorly written scripts/content can cause high server load as well on your domain(s). Pls. try to investigate your domain - specific log - files for further investigations and tryout as well a different PHP - handler.
Pls. make sure, that if you use ".htaccess" - files, that the ( possible ) additional nginx directives are correctly setup and don't cause loops or 5xx and 4xx - errors. ;)
Check as well possible modsecurity issues on your domain ( if in use ).
