I don't know.... it is just what I saw when I enter my site.

I used Bitnami to set up this Magento Site, and it was functioning normally, but shows this error after several days.

In which I didn't do anything additionally.

As the issue may have to with your internal configuration I would recommend reviewing this third-party guide detailing general troubleshooting steps for this error. 

I would also suggest to ensure that your firewall and ports are correctly set up on your server and project following this troubleshooting guide.  You can check for open ports on your server with the command below:

netstat -tulpn

Thanks for the solution!!

I went through part of the guideline, and find the below notification during so. Therefore, I think it happen due to limit excess... but I even didn't. build anything on it yet... strange...

Anyway, according to the guideline, one of the fix is to restart router;I am so lazy that I restarted the instance, and it works again!!!

Glad to know that your issue is resolved.I had a look at the aforementioned document for troubleshooting 503 Backend Fetch Failed. Found there is an option to reboot the routers and if that does not work, reboot the PC or whichever device you are using.

However, you can monitor memory utilization of VM. I have found a Stackoverflow thread on monitoring memory usage of VM instances, you can take a look.

You can also take a look at the document on changing the machine type.
