Today, while I was searching, I was suddenly confronted with an error message from Google server, that was a 404 not found error with this contents :
Not Found The Requested URL /search was not found in this server.
Apache/2.2.22 (Debian) Server at www.google.com Port 443 (notic)
When I refreshed the page that error message was cleared and I saw the search results.
That error was acquired when google was trying to keep this information hidden.
It's true!? Anyone have any idea?!

If a visitor gets 404 error, nothing is written in apache error.log. In access log it appears like this:
GET /qqq HTTP/1.1" 404 409 "-"
And nothing in error.log. I have tried everything about LogLevel. As I understand, it is because that 404 page is custom page like
ErrorDocument 404 /new404.html
But I run search through all /etc/apache2 for text "404" in files and nothing was found there (instead of commented lines). What can be the problem? Or maybe I can somehow disable custom 404 page in .htaccess file? Or any other ways to display 404 errors in error.log?
As the person who filed the Apache bug which demoted 404 from Error to Info level as of Apache 2.4.1, here's the justification:
In production HTTP servers open to the Internet, 404s happen all the time. Malware, scanner scripts, and all sorts of other things probe Web servers for vulnerabilities or just because they can, and these things would all trigger errors which will end up being logged somewhere if the appropriate error level is set.
Most production Web server admins are content with seeing 404s in their access logs (which are logged right alongside 200s and 30x redirects), and want to see real server problems -- things they have control over fixing -- in the error log. The logging of 404s in error.log can, in some servers, be so much log spam that it drowns out legitimate problems needing the administrator's attention.
404 is a content issue, not a server issue. So my recommendation is to look in your access.log (or equivalent) for them. If you really want content related issues logged in error.log, you need to set LogLevel core:info. This will give you 404s there, and a few other kinds of content-related error messages too.
404 "errors" don't normally appear in the Apache error log, regardless of whether you have a custom ErrorDocument defined or not.
A 404 error is not strictly a server error. It's an expected HTTP response, so it naturally appears in the access log (as you have stated), not in the error log. The "404" is the HTTP response code, not a server error code.
However, you should be able to enable additional "information" messages in your error logging (eg. LogLevel info on Apache 2.4) to get this "information" in your system error log:
[Mon Feb 06 08:00:00.090525 2017] [core:info] [pid 13876:tid 1748] [client 203.0.113.111:54493] AH00128: File does not exist: /home/user/public_html/path/to/file
Note, however, that there is no mention of "404" - which maybe why your searches came up blank. This LogLevel should not be maintained on a production server.
Maybe this helps somebody...
I had zombie apache instances running (with a slightly different config loaded), and every other request for a static resource defined using an Alias was 404-ing.
Killed the zombies and all good...
404 is a server response, not a error.
You can get the 404 log doing something like:
cat /var/log/apache2/access_log | grep " 404 " | awk -F' ' '{print $4," ",$5,"-",$7}' > /root/404.log
and adjust the awk as you need!
I am working on a php website. I am working on it using Aptana with XAMPP. I recently changed my htaccess file to force my site to use https on the localhost. I haven't yet implemented a ssl certificate. When I try to access a webpage now, I am directed to a page that says:
Object not found!
The requested URL was not found on this server. If you entered the URL
manually please check your spelling and try again.
If you think this is a server error, please contact the webmaster.
Error 403
localhost
Apache/2.4.10 (Unix) OpenSSL/1.0.1j PHP/5.6.3 mod_perl/2.0.8-dev Perl/v5.16.3
I found some solutions to this but I really want to know why this is occurring. I know that I can change the httpd.conf file to fix it but I still don't understand what is happening.
Morning
I have a domain, www.example.com, which is a Contao 3.1.3 CMS website on Linux Apache.
I have just purchased and installed SSL certificate for the domain.
When I go to https://www.example.com (or https://example.com) all works fine.
when I try one of the other pages on the domain, http://www.example.com/folder/page.html all is fine, but with https://www.example.com/folder/page.html
, I get an error:
The requested URL /folder/page.html was not found on this server.
This does not happen with pages in the admin area, which all appear fine via https
Console log shows:
Failed to load resource: the server responded with a status of 404 (Not Found)
What is the solution to make all pages appear ok under https
I tried this: https://community.contao.org/de/showthread.php?43595-SSL-und-Contao
but it didn't help
I also checked https://www.sslshopper.com/ssl-checker.htm to see if the error is with the ssl certificate, but no problems found there.

Problem cannot be on the SSL. From your explanation I would suggest you play around with disabling folder urls and url rewrite in the settings. Then make sure the page exists. I am sure from here you will be able trace down the problem.
Make sure also in the root page, the 'domain' field is on https if its set.
You can restore your folder and url rewrite settings when all is well
The issue was actually with the directives on the virtual server.
Background:
OS: ubuntu
Web Server: apache2
What works:
I can ping the server's elastic IP (and receive a response)
I can ssh into the server
What doesn't work:
I cannot get any sort of http response from the server
Expected Behavior:
When I go to http://ec2-XXX-XX-XXX-XXX.compute-1.amazonaws.com/, it will serve my page, or at least give me a 404 that I can debug
Actual Behavior:
When I go to http://ec2-XXX-XX-XXX-XXX.compute-1.amazonaws.com/, it says "Oops! Google Chrome could not connect to ec2-XXX-XX-XXX-XXX.compute-1.amazonaws.com". It doesn't even give me a 404.
Rant:
Clearly the server is there because I can ssh in to that exact address and I can ping that exact IP and get a response. But when I go that exact address in my web browser it's as if it never makes it to the server. Or it's as if Amazon isn't letting http requests through, but in my security group I am clearly specifying that http requests from all sources are allowed through. Apache is definitely running, my document root is definitely set up properly, and my error and access logs don't give me anything.
Is there any sort of log in between Amazon and the server, or in between requests making it to the server and being received by Apache that would specify why it's returning "not found" rather than a 404. Can I make my Apache logs more verbose?
Thanks in advance! I've spent hours on this....
Turns out apache was set to listen on port 8080 rather than port 80, so if you encounter this problem, try taking a look at what apache's listening to.
I'm having a problem implementing custom 404 error pages. my setup is a front-end apache 2.2.6 proxy request other than static file to the backend app server(apache 1.3.36)
i send 404 header back along with error page when user request a non-existing page to the backend server. I do get the error page back but somehow the backend apache server injects its own 404 not found page in the error page as well.
here is what injected to the not found page by apache:
Not Found
The requested URL /product/8jd4776 was not found on this server.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
Apache/1.3.36 Server at www.example.com Port 8888
any idea why this is happening?
set "ProxyErrorOverride On" with ErrorDocument in the front-end apache server solve the problem.
The content length of your custom 404 message must be 512 bytes or more.
