I'm asking about an issue on a Wordpress website, that serves on an Ubuntu 18.04 behind of a WAF service.
The server was working for 1 year. 4 days ago I tried to upload a file and I got
upload_max_filesize and other values on configurations are about 2G.
First of all, I checked VM configs and I found out VM memory reduced to 4G. After increasing the memory amount, I did a check on Vestacp for the PHP, Nginx, and Apache configs, and they had no changes. Then I tried to upload, but this time on the local network and file uploaded successfully!
here are the questions: Did I miss anything, while I checked the configurations? Is the WAF the reason of the problem? Is it a possibility that reducing and increasing the VM Memory amount, causing the problem? And at last, how can I fix this?
Can someone explain the Juniper strategy and why it has done this?
