WP Import Pro Gateway 504 error

You may have that issue when trying to use this WordPress plugin or simply going into “import setting” of the plugin. This happens because you need to increase timeout in ngxin/proxy.

Recommend settings can be found here: https://www.wpallimport.com/documentation/troubleshooting/server-configuration/

In my experience when using this plugin with Nginx + Fastcgi. I need to increase this limit below for it work. fastcgi_read_timeout 300;

location ~ .php$ {
fastcgi_split_path_info ^(.+.php)(/.+)$;
fastcgi_pass php-fpm:3000;

            fastcgi_index index.php;
            include fastcgi_params;
            fastcgi_read_timeout 300;
            # Enable HTTPS to avoid mixed content over https
            fastcgi_param HTTPS $fastcgi_param_https_variable if_not_empty;

    }

You can also increase this limits temporary.

proxy_connect_timeout 600;
proxy_send_timeout 600;
proxy_read_timeout 600;
send_timeout 600;

Please remember that increasing the limits is always the best practices but sometimes necessity. You are allowing your server run process request for much longer so if you got any issues on the website which can be exploited it may decrease your server performance if the request with issues run for a longer time taking resources.

Normal user won’t long 1-2minutes for page to load. It is just an example 🙂

Setting up Swarmpit with Traefik on non standard port

The following configuration will work. This will create an extra entry point on 8843

So your site will be accessible on https://yoursite.com:8443

Your swarmpit.yml file

traefik.http.routers.swarmpit-https.rule=Host(${DOMAIN_SWARMPIT?Variable not set},${DOMAIN_SWARMPIT_FAILOVER})
#- traefik.http.routers.swarmpit-https.rule=Host(${DOMAIN_SWARMPIT?Variable not set})
– traefik.http.routers.swarmpit-https.entrypoints=websecureextra
– traefik.http.routers.swarmpit-https.tls=true
– traefik.http.routers.swarmpit-https.tls.certresolver=le
– traefik.http.services.swarmpit-https.loadbalancer.server.port=8080

Your traefik.yml configuration file

–entrypoints.websecureextra.address=:8443

–entrypoints.websecureextra.http.tls=true

CISCO 7940 enable to provion on PBX looking for SEP config files

This was caused because the phone was connected to a POE switch and could not upgrade to firmware to the one provided by PBX server. Once connected the phone with power adapter instead it has upgrade the firmware and was looking for correct SIPxxxxxxxxxxxx.cnf files from FreePBX system.

How to disable SSL verification on Yii2 Swift mailer

This is not a good practice but if you are using wildcard certificate then the name can't be authenticated correctly.
You need to use the following configuration on web.phph in Yii2 to make it works.

'mailer' => [
            'class' => 'yii\swiftmailer\Mailer',
            // send all mails to a file by default. You have to set
            // 'useFileTransport' to false and configure a transport
            // for the mailer to send real emails.
            'useFileTransport' =>  false, // change to false to send emails externally.
            'transport' => [
                'class' => 'Swift_SmtpTransport',
                'host' => 'x.x.x',
                'username' => 'x-x',
                'password' => 'xx',
                'port' => '587',
                'encryption' => 'tls',
                'streamOptions' => [ 
                    'ssl' => [ 
                        'allow_self_signed' => true,
                        'verify_peer' => false,
                        'verify_peer_name' => false,
