HTTP 504 is a gateway timeout error on your server.

Thanks. I have increased those three values then restart apache2. Same issue. New console log:

\

What are ALL the possibilities that affect this issue?

If you click on the error in the Network tab, it will show the headers and response in tabs. What is the complete response? What were you doing when the error occurred? Step by step including permissions of the user and any post content.

Though it appears to be polling for new vB Messenger data for the user when it is failing. You can temporarily turn off vBulletin Messenger to remove that polling. Settings -> Options -> Private Messaging and vBulletin Messenger Options. Set Enable vB Messenger to no.

Network tab has no error, only in console

More information... I got the text/ error and the response:

Code:

<html>
<head><title>504 Gateway Time-out</title></head>
<body bgcolor="white">
<center><h1>504 Gateway Time-out</h1></center>
<hr><center>nginx/1.12.2</center>
</body>

I'm just a bit concerned by this post:

How to remove .html off the request url? - vBulletin Community Forum

https://www.vbulletin.com/forum/forum/vbulletin-5-connect/vbulletin-5-connect-questions-problems-troubleshooting/vbulletin-5-support-issues-questions/4398129-how-to-remove-html-off-the-request-url?p=4398224#post4398224

Since upgraded from vb4 to vb5, most users has an old url with a .html at the end. I need to remove that before it called the routing.php. How to achieve this? I tried to add this in the .htaccess file: # Main Redirect RewriteCond %{REQUEST_URI} !\.(gif|jpg|jpeg|png|css)$ RewriteCond %{REQUEST_FILENAME} !-f

If I've read this right, you've editing the routing.php file. This isn't really a very good idea and I suspect it may be no coincidence that you're now experiencing issues.

In the first instance I would restore the file to its default state, clear the system cache, and see if the issue persists.

While that's correct, I have no issue on local dev laptop. This is what I added, else there is a better way:

Code:

// routing.php on line 120 of vb 5.4.3 inside the try block

            if ($route === false) {
                global $vbulletin;

                $path_array = explode('/', $path);
                // Get last element in array
                $query_string = end($path_array);
                // Separate old nodeid from string
                $id_string = explode('-', $query_string);
                // Use oldid
                $oldid = $id_string[0];

                if (intval($oldid)) {
                    $query = $vbulletin->db->query_read(
                        "SELECT
                            nodeid,
                            oldid
                        FROM
                            node
                        WHERE
                            oldid = $oldid
                        AND
                            urlident
                        IS NOT NULL
                    ");
                    $result = $vbulletin->db->fetch_array($query);
                    $url = vB_Api::instanceInternal('route')->getAbsoluteNodeUrl($result['nodeid']);
                    header('Location: ' . $url, true, 301);
                    exit;
                }

                // Continue as normal if $oldid is not an integer <-- DO NOT REMOVE THIS COMMENT
            }

If you look at the response tab when the error is triggered, it will have the raw JSON which is what is triggering the error. You're showing the preview tab which isn't helpful as a screenshot. Need to see the entire JSON that is returned.

**Cruisey** · Thu 13 Sep '18, 1:13pm

Ok ill see what is causing this on the server as the response is of a server issue:

Code:

<html>
<head><title>504 Gateway Time-out</title></head>
<body bgcolor="white">
<center><h1>504 Gateway Time-out</h1></center>
<hr><center>nginx/1.12.2</center>
</body>
</html>

Also, when you refresh the browser, the content is shown so I guess an ajax response gone wrong or never returned in time to the browser?

**Wayne Luke** · Fri 14 Sep '18, 9:30am

As stated above, the error doesn't seem to have anything to do with actually creating content. Based on your images, it appears to be due to polling to see if the user has new private messages. Without the full JSON, I can't see where that error is occurring.

**Cruisey** · Fri 14 Sep '18, 10:50am

Ive disable vB Messenger but same issue.

**Cruisey** · Mon 17 Sep '18, 12:21am

Wayne Luke If you could point me in the right direction, what file/controller executes the sql query to insert the data into the database? I could do a hack until we sort the server issue out. Instead of waiting for a response, we'll refresh the page regardless. Is that in a js minified file somewhere; the footer-rollup-543,js?

**Wayne Luke** · Mon 17 Sep '18, 8:29am

To be honest, I don't know what file the error is being caused by because you haven't provided the information that I asked for.

I did provide it. I figured how that section works, in createcontent.php inside a function called "createNewNode". Basically, the server times out without sending back a json; it returns the html

The "$output" is html, not an array. This was actually the server timing out. We are using reverse proxy so somewhere when the data is saved in the database, data takes long to return for the js to update. There's no nodeid nor retUrl. I can confirm that this is a server related issue and not vBulletin. Many thanks for your continued support.
