Issue Connot access Plesk Web interface anyore - 404 Error

[QST]

Hi!

I have installed the latest Plesk update a few days ago and on that day everything worked fine. Today, after trying to login into the Plesk Web interface, I get a 404 error message.

Error log shows:

[error] 14743#0: *4 open() "/opt/psa/admin/htdocs/index.html" failed (2: No such file or directory), client: 127.0.0.1, server: , request: "GET /index.html HTTP/1.0", host: "127.0.0.1:8443"​

Installed version: 17.5.3 Ubuntu 14.04 1705170317.16

Web-interface is using an nginx proxy command to redirect to the 8443 port (hence host address is 127.0.0.1). Before that everything worked just fine.

plesk repair installation - did not help

Try:

# plesk installer --select-release-current --reinstall-patch --upgrade-installed-components
# plesk repair installation

Hi IgorC, thanks a lot for the prompt reply. It did not help, the error persists. I have noticed that in sw-engine.log there is the latest record:

[21-Jun-2017 02:00:25] NOTICE: Reloading in progress ...

​

It looks like the config file was overwritten by someone/something, doesn't it?

Just to add, my nginx redirect command looks like this:

location / {

allow xx.xx.xxx.xxx/24;
 deny all;

proxy_pass https://127.0.0.1:8443;

}
