Nginx stops automatically at particular time



I am facing a strange issue where nginx stops/crashes at around 12am(12am-1am) and 12pm(12pm-1pm) everyday UTC time. I am monitoring(up/down) a website using a website monitoring tool. When website is down, at the same time there is an entry in nginx error log:


2018/07/02 12:16:54 [notice] 2288#2288: signal process started



When I check nginx status using "sudo systemctl nginx status" it says:


Active: inactive (dead) since Mon 2018-07-02 12:16:54 UTC; 19min ago



So, I have to restart nginx to make the website working and again the same thing happens next day.

I figured out the issue myself. I checked syslogs and it was certbot that was trying to renew certificate at a particular time. Fixing certbot fixed the issue.





You should add the steps you took in order to figure out the problem, might help someone else in the future.

PHP contact form sending but not receiving emails

PHP contact form sending but not receiving emails I have created a contact form using PHP to send the data. The form seems to send fine as there are no errors and success message appears, however I am not receving the emails into the designated inbox. I am using PHPMailer as I originally tried just using the php 'mail' command which I now understand is a bit hit and miss. I cannot see why I would not be receving the emails so I would be very grateful for any help that could be given. I'm quite new to PHP so please be patient with me :) <?php use PHPMailerPHPMailerPHPMailer; use PHPMailerPHPMailerException; $msg = ""; if (isset($_POST['submit'])) { require 'phpmailer/src/Exception.php'; require 'phpmailer/src/PHPMailer.php'; require 'phpmailer/src/SMTP.php'; function sendemail ($to, $from, $body) { $mail = new PHPMailer(true); $mail->setFrom($from); $mail->addAddress($to); $ma...

Do graphics cards have individual ID by which single devices can be distinguished?

Do graphics cards have individual ID by which single devices can be distinguished? I have several graphics cards of the same manufacturer and same model and I want to distinguish them not only by the pcie socket they reside in but by some individual value I can read from the hardware. Is there such value and if so what would it be called and how could I access it? Right now I'm using modern nvidia cards (10xx series) and nvidia inspector.but I'd prefer if there was any value that was also applicable to amd. I have programming and scripting knowledge. I am running Windows 10 1 Answer 1 This is a powershell example to pull information from video cards. The DeviceID is supposed to be unique but only if the manufacturer supports Windows Display Driver Model (WDDM). (I copied this directly from docs.microsoft.com) $strComputer = "." $colItems = get-wmiobject -class "Win32_VideoC...
