Cloudflare Error 521

Keywords: WordPress - Amazon Web Services - Technical issue - Domain Name (DNS)
Description:
I'm having trouble with my server for some reason I can't log into my wp-admin. Upon investigation www.leparadis.us I found a server error 521 using Cloudflare. I'm a novice when it comes to server terminal issues and I did see some old threads about error 521. I wasn't able to find https://community.bitnami.com/t/521-error-with-cloudflare/30655

Find the line

LoadModule reqtimeout_module modules/mod_reqtimeout.so

and turn it into:

#LoadModule reqtimeout_module modules/mod_reqtimeout.so

is there any other way to solve this issue on Amazon web service? or is it a different command line for amazon web servers?

Hi,

Are you able to access the instance without using Cloudflare redirection? That is, using the IP address shown in the AWS Console? This would help us see if the issue is in the instance or not.

Hey Javier,

Thanks for answering my post, yes I'm able to log into the terminal instance from the IP address shown on my aws console.

Do you need the Ip address?

Hi,

What I meant was not using ssh but accessing WordPress directly using that IP. Are you able to see the blog and login to wp-admin when accessing without CloudFlare?

Hi
I'm not able to gain access to my website with .com/wp-admin.

Still results in an error 521. I'm hoping my instance didn't crash or at least still have my backups on bitnami.

Thanks again for taking a bit part of your day to answer my question,

Hi,

Let me insist on the same. If you open your browser and put the IP address (not the domain name .com) that you see in the Public IP section in AWS Console, do you see any error?

I tried inputting the server IP Address no luck and even the amazon.com link and also no luck.

I'm running word press version 4.7-0. I believe its just the communication between my server to my domain. I can gain access to my instance.

Hi,

This doesn't look good. It looks like there is something strange going on with the instance, not with CloudFlare. Could you execute this command?

sudo /opt/bitnami/ctlscript.sh status

In addition, we have a Support Tool that will gather relevant information for us to debug the issue. Could you please download and execute it on the machine where the stack is running by following the steps described in the guide below?

Looks like my results are:
php-fpm already running
apache not running
mysql already running

Hi,

Just as I thought, something must be wrong with the Apache configuration. Could you try executing sudo /opt/bitnami/ctlscript.sh start apache? Also, try executing apachectl -t to see if there is any error in the Apache configuration. In addition, please execute the Bitnami Support Tool so we can get more information about your configuration.

Hi,

Did you modify the /opt/bitnami/apps/wordpress/conf/htaccess.conf file? It looks like there are some syntax errors there.

Regarding bnsupport, installdir is a placeholder in the documentation, you should use /opt/bitnami instead.

umm, i believe I did a long time ago to direct the IP or the Amazon address to my actual domain.

Hi,

Just as it says, there is a </Directory> label missing at the end of the file. Could you try adding that and see if it works now?

Sorry to jump on this convo. This error is also happening to me but my results were:

php-fpm already running
apache already running
mysql already running

Should I open a new thread?

Hi @rubensantos1,

Yes please, we prefer to maintain each case in different threads because the issue and the solution maybe are different and could invite confusion among different users.
We thank you if you create a new one for your case, thank you very much.

Best regards,
