My website at is not showing up as usual. Its error message, comes back as unexpectedly closed the connection. I ran the Bitnami diagnostic tool it returns many different error ranging from pagespeed and my disk space being 53% full. I just want to figure out what the solution is.

Hello @chetd90,

Did you check the suggestions from the support tool?


Found recent Pagespeed related error messages in the Apache error log:

[Wed Jan 05 16:47:08.679439 2022] [pagespeed:error] [pid 25255:tid 140318527715072] [mod_pagespeed **ip_address**-0 @25255] PageSpeed Serf fetch failure rate extremely high; only 227 of 639 recent fetches fully successful; is fetching working?

We suggest disabling pagespeed and check if that improves the behavior. Please check the following guide to disable Pagespeed:

Please check the following guide to troubleshoot server issues:

A high number of incoming requests originate from one or more unique IP addresses. This could indicate a bot attack. The following guide shows how to check for and block suspicious IP addresses.

Ok, I was attempting to disable pagespeed using http.conf and for some reason I can’t save the file. I guess I have to change the permissions on the file.

Please take a look at this guide:

I’ve already denied the IP address of the bot.
