Description:
I am running bitnami magento on AWS apache stack. I am using ELB for SSL.
I am getting these errors:

[authz_core:error] [pid 16054:tid 139871473542912] [client 127.0.0.1:36716] AH01630: client denied by server configuration: /opt/bitnami/apps/mag$

Hi @sales4,

Thanks for providing us with the Bitnami Support bundle. I can see in the Apache error_log that the full error message is:

client denied by server configuration: /opt/bitnami/apps/magento/htdocs/app/etc/config.php

This is an internal path and should not be accessible directly, hence is blocked in /opt/bitnami/apps/magento/conf/htaccess.conf file:

<Directory "/opt/bitnami/apps/magento/htdocs/app">
<IfVersion < 2.4>
    order allow,deny
    deny from all
</IfVersion>
<IfVersion >= 2.4>
    Require all denied
</IfVersion>
...

Could you let us know that URL are you trying to access when using the ELB? Could you please provide some more details about the configuration that you used? Please note that you can find instructions on how to configure this in this page to our documentation.

Also, could you check if Magento works correctly when accessing directly to the instance's public address / hostname?

Hi, the URL is:

https://www.combatstocks.com/

The configuration - well I subscribed to the Amazon Marketplace Magento instance by Bitnami. Can you be more specific as to the configuration details you are asking about?

The instance's public DNS is:

ec2-54-159-131-65.compute-1.amazonaws.com

Trying to load that results in "Connection Timed Out".

I did follow all the instructions for creating the ELB at the link you provided (before posting here) and the ELB is functioning correctly, as is the AWS secure certificate, which you can see if you go to https://www.combatstocks.com

However, when I try to run:

SetEnvIf x-forwarded-proto https HTTPS=on

I get an error saying "SetEnvIf: Command Not Found"

Thank you,
Andrea

Just realized that I was to add that SetEnvIf line to the httpd-prefix.conf file, which I did, then restarted apache, made no difference. Still getting the error.

Hi @sales4,

Sorry for not being clear enough, I meant the configuration details of the ELB, but I think I have a clue of what could be happening.

Could you check if the security group of your instance (not the one for the ELB) allows inbound traffic on port 80? If not, could you check if adding a rule that allows it from Anywhere solves the issue? In case you don't want to allow accessing your site via the instance IP / hostname, instead of Anywhere you could use Custom and specify the ELBs security group so it's only accessible for the ELB.

In any case, I would try first with Anywhere and confirm this is the actual root cause of the issue.

I added a new rule allowing inbound http traffic on port 80 from anywhere, but that did not solve it. See attached screenshot.

Thanks.

Hi @sales4,

I can see how this URL

is not returning 502 error anymore, now showing what seems to be your Magento application. Could you please confirm the issue is solved? Did you need to apply any further changes or was it enough changing the Security Group rules and waiting for the changes to be effective?

sales4 2019-02-14 18:20:13 UTC #8

No, it was resolved because I paid a developer I found on upwork. He had to redo my ELBs to get all of that configured correctly.

Also, I cannot figure out how to get thumbnail images to show. Where do I control this setting?

Thanks

Hi @sales4,

Thanks for the information.

Regarding the thumbnail issues, is it possible that you need to refresh the Magento cache? You can find how to do it in this section of the docs. If this doesn't work, I've also found some links that suggest republishing the static assets:
