Resolved all sites down, browser downloads a 0kb file called 'download'

[Erwin Fiten]

Since this morning, all my sites are down, and download a 0kb file, instead of showing the index page.
This is for apache sites? the ones with nginx caching give a '502 Bad Gateway' error.

PLESK backend is working.

Plesk Onyx for Linux
Version 17.8.11 Update #60

Already did :

• service nginx restart
• service apache2 restart
  
• service sw-engine restart && service sw-cp-server restart

Didn't restart the server yet, afraid of losing data (backup is 1 day old.

Anything I can do ?

NGINX example : https://www.dansstudiocrescendo.be/
APACHE example : https://www.greetreekmans.be/

Have you tried:

plesk repair web

Also, anything interesting in /var/log/apache2/error.log?

 

[Erwin Fiten]

did a repair without luck. Here are some parts from the errorlog :

OK, next thing to try:

plesk installer --select-release-current --reinstall-patch --upgrade-installed-components

 

[Erwin Fiten]

I had custom settings in '/usr/local/psa/admin/conf/templates/custom/domain/nginxDomainVirtualHost.php' that I already disabed.
Did the latest update, as you requested, without luck :

Patching file (481 of 483) /usr/local/psa/admin/htdocs/javascript/jsw.min.js.map
Patching file (482 of 483) /usr/local/psa/admin/plib/PartnerCentral/ApiClient.php
Patching file (483 of 483) /usr/lib/plesk-9.0/postfix-local
All patches were applied.


Patches were installed successfully.

The changes were applied successfully.

 

[Monty]

I'd check /var/log/syslog or /var/log/messages for anything unusual ("failed", "error" etc.) as the next step.
Then you can also perform a "plesk repair all"
And finally, reboot your server.

 

[Erwin Fiten]

Didn't find any significant errors inside the logs, so i restarted the server (after +350 days uptime), and it looks OK now.

Thanks !
