One explanation for –> An unexpected error occurred…..

I’m not sure why the coder of plugin-install.php decided to keep all users in the dark as to the reason why this message is displayed (“An unexpected error occurred. Something may be wrong with www.ads-software.com or this server’s configuration.”) but I’ve found that it does (at least in this case) return a perfectly reasonable error response.

In this case, the api call times out but I only found that out by manually forcing it to display the error msg (something like ‘http_timeout’). I changed
‘timeout’ => 15 to ‘timeout’ => 25 in the request below and everything was fine.

if ( false === $res ) {
                $request = wp_remote_post('https://api.www.ads-software.com/plugins/info
/1.0/', array( 'timeout' => 15, 'body' => array('action' => $action, 'request' =
> serialize($args))) );
                if ( is_wp_error($request) ) {
                        $res = new WP_Error('plugins_api_failed', __( 'An unexpe
cted error occurred. Something may be wrong with www.ads-software.com or this server&#8
217;s configuration. If you continue to have problems, please try the <a href="h
ttp://www.ads-software.com/support/">support forums</a>.' ), $request->get_error_messag
e() );
                } else {
