404 not found error after applying HTTPS

Comocozy

Hi,

I installed Flarum on AWS successfully. Users could access through the HTTP.
For secure connection, I've installed the SSL on the AWS and changed the url from 'http' to 'https' in config.php.
Then, HTTPS access works - I can see the main page of the flarum.
However, 404 error occurs when I start a discussion or try to access old posts.

POST https://[domain name]/api/discussions

<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>404 Not Found</title>
</head><body>
<h1>Not Found</h1>
<p>The requested URL /api/discussions was not found on this server.</p>
<hr>
<address>Apache/2.4.18 (Ubuntu) Server at [domain name] Port 443</address>
</body></html>

Here is a snippet of my .htaccess file regarding mod_rewrite.

<IfModule mod_rewrite.c>
  RewriteEngine on
  #HTTP to HTTPS
  RewriteCond %{HTTPS} !=on
  RewriteRule ^/?(.*) https://%{SERVER_NAME}/$1 [R,L]
...

I've also tried to modify VirtualHost (000-default.conf and default-ssl.conf), but the result was same.
It would be great if I could get some references regarding flarum installation with https.

Thanks.

If it's giving a 404 the url rewriting probably isn't set up correctly. Please also refer to to this guide to identify a common cause.

luceos Thanks for your reference.
I've checked them all but still 404 error occurs.
I'm sure my SSL configurations on apache2 are correct because those are working in other website.

/etc/apach2/sites-available/000-default.conf

<VirtualHost *:80>
    RewriteEngine On
    RewriteCond %{HTTPS} off
    RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}
    ...
</VirtualHost>

/etc/apach2/sites-available/default-ssl.conf

<IfModule mod_ssl.c>
    <VirtualHost _default_:443>
        ...
        SSLEngine on
        SSLCertificateFile    [certificate file path].crt
        SSLCertificateKeyFile [certificate key file path].key
        SSLCertificateChainFile [bundle key path].crt
        ...
    </VirtualHost>
</IfModule>

No modification in /var/www/html/.htaccess.

/var/www/html/config.php

<?php return array (
  'url' => 'https://xxx.xxx.xxx',
  ...
?>

Do you think rebuilding the flarum would be the right approach to solve this issue?

Does the forum work when using http only, even if your certificate is installed try using the non-ssl link in your config. We first need to identify whether url rewriting works at all.

luceos Sorry, this issue is not related with Flarum.
I should add 'AllowOverride All' in default-ssl.conf as well.

<IfModule mod_ssl.c>
    <VirtualHost _default_:443>
        ...
        <Directory "/var/www/html">
            AllowOverride All
        </Directory>
        ...
    </VirtualHost>
</IfModule>

Your tips helped me debug this issue. Thanks!

I'm having the exact same problem, but unforutanly I'm not able to find "default-ssl.conf" and change the permissions.
My Flarum website is currently hosted at Namecheap, and I do have access to SSH.
Has anyone else faced this problem, if so, can anyone help me?

Thanks in advance!
