Hi @arcaikastore

Thanks for providing the ID! I was able to look at the report generated by the tool and I have some follow-up questions.

Were you able to solve the issue? I am able to access your site at the moment and do not experience any problem. Is this a recurrent problem or something that just happened once?

This error is caused when Varnish cannot reach the backend trying to be reached is unavailable, despite Varnish’s efforts to communicate.

If this has only happened once, it may be due to a sudden increase in the traffic the site receives, which ended up consuming all the available resources and hence leaving Magento unresponsive.

Additionally, I have seen there are several recurrent errors in your Magento log files:

$ cat /opt/bitnami/apps/magento/htdocs/var/log/exception.log

I have found a similar thread in the official Magento support forum, could you please take a look at it?
