503 service unavailable error on webserver

AaronOsmer
Recently I have been getting the occasional 503 error on my web server. It seems to be an issue with the UTM Webserver protection, as when I go to the website locally by the server ip address everything is fine. This is a sporadic issue, and happens probably 1 out of 5 times going to the site.

Below is the error log from the Web Application Firewall:

    But for me, I think most of the people who are facing Error 503 are just service unavailable Error 503.

    Refreshing or reloading the page might help if it's a temporary error.
    Try restarting your Wifi modem.
    Contact the admin(startor) of the website.
    If that's because of popularity then site admin might be searching some fix for that error, so come back later.
    If you want a clear insight of troubleshooting the error then please try to check the following blog post of mine. Hope this works.
