If you get an err_connection_refused wordpress error, you should first try restarting your server, as this can often fix the problem. If the problem keeps happening, you can try increasing your server's memory limit. This can help if the problem is caused by a lack of resources. You should also try repairing the database, which can be done through the WordPress dashboard. Additionally, you should check your plugins and themes to make sure they are all up-to-date, as outdated components can cause this error.
