Description:
This post refers to an old post created on 20-Jul-20

Then again a post dated 09-Aug-20

In fact we are facing this issue for the past 5 months in the website mymbt.net. We had been getting the "ERR_TOO_MANY_REDIRECTS" error once we run the bncert-tool to do the redirection. After two posts in the Bitnami forum which went unresoled. We have refered it to the Microsoft Azure Support team. After MS support the admin dashboard rediected from HTTP to HTTPS after changing in the below configurations Admin Dashboard from No to Yes.

a. Use Secure URLs in the frontend.
b. Use Secure URLs in the Admin.
Checked the offload header as SSL_OFFLOADED.

The redirect from HTTP to HTTPS doesnot work on main page i.e. mymbt.net with below .htaccess file –

File 1-
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteCond %{HTTPS} off
RewriteRule ^ [https://%25%7Bhttp_host%7D%25%7Brequest_uri%7D/]https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301,NE]

File 2-
RewriteCond %{HTTPS} off
RewriteRule ^ [https://%25%7Bhttp_host%7D%25%7Brequest_uri%7D/]https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301,NE

Currently it stands like this:-

The site works perfectly when we enter the secure URL directly i.e. https://www.mymbt.net
The site will not auto redirect when unsecure URL is entered i.e. http://www.mymbt.net
The admin of the site i.e. Magento Admin will auto redirect. So the URL mymbt.net/admin takes automatically to https://www.mymbt.net/admin

In our post dated 09-Aug-20 in the same forum we were told to create a similar instance in Azure. We couldnot locate Ububtu 16.04 image in the Bitnami repository on the Azure marketplace. Maybe it had been deleted. Later we found one that we had taken for testing in one of our tenents in Azure. We did as suggested by @michiel. Strangly the new site in the new instance gave the same "ERR_TOO_MANY_REDIRECTS" error. We have hosted the domain contient.in on the said instance. We did run the support tool in the new instance as well.

Dear

@michiel
@gongomgra
@amoreno

This problem was attended to all of you and has remained unresolved. It has been 5 months. Please help. We have been paying Microsoft for hosting for the past months and MS Support has failed to resolve too. We need to decide if we need to continue with Bitnami as there is no support. We have tried to create another fresh instance of the latest Bitnami Azure stack and have followed the exact steps and found that the problem to be replicated. I can share the support tool code for that too. So maybe it is a problem with the stack or a problem with the documentation. In this context we need to decide any one of the following options:-

I can share the username and password of my instance for your team to find the problem directly
I can move my instance to another fresh instance is the existing one is completly broken and cannot be fixed
I can completly move from Bitnami/MS Azure to other providers like GoDaddy

Whichever is the option we need to decide on it fast.

Hi @debtanubiswas,

I just reproduced the issue and I'm working on getting more information. Sorry for the delay here and I hope to have a fix soon.

Hi @debtanubiswas,

I have some news about the Magento + Bncert configuration. If you run the Bitnami HTTPS configuration tool setting the non-www domain and use the default parameters (force https and the www redirection), the application is configured with a "incorrect" domain (the non-www one) when Apache redirects to the www one. That's one of the causes of the redirect issue. In that case, you can reconfigure the application to use the www domain

sudo /opt/bitnami/apps/magento/bnconfig.disabled --machine_hostname YOUR_WWW_DOMAIN_HERE

I could access the main site after applying this change. However, I got another redirection loop when accessing the admin site. In this case, I needed to modify the app's configuration to force https in the admin site

cd /opt/bitnami/apps/magento/htdocs
sudo ./bin/magento-cli config:set web/secure/use_in_adminhtml 1
sudo ./bin/magento-cli cache:clean
sudo ./bin/magento-cli cache:flush
sudo rm -rf var/cache/ var/page_cache/

I could access the admin panel after running these commands.

However, I could not configure Varnish and HTTPS, it's generating the redirection loop again. Can you undo the Varnish and HTTPS configuration changes (https://docs.bitnami.com/aws/apps/magento/administration/configure-use-varnish/#use-varnish-tm-with-ssl) and check the commands I posted above to recover your site?

If you continue running into issues, please run the Bitnami support tool again and run these commands as well

cd /opt/bitnami/apps/magento/htdocs
sudo ./bin/magento-cli config:show

Dear Jota,
Thank you for your reply. I was relived to get a response from the team. Well I have followed the exact steps as you have said but with no results. Have tried to use varnish with SSL but found that the lines are already added. Then I have configured the www-domain to the application and ran the bncert-tool. The result was the same loop. To let you know if I have followed the right steps I have screen recorded the session in a 4 minute video. The URL is here

The code from the Bitnami support tool is as follows:-

Thank you.

Hi @debtanubiswas,

I told you to undo those changes and run the commands I posted in my previous post.

If you deploy a new VM, you will basically need to avoid configuring Varnish with SSL.
- Generate the certificate
- Run the bnconfig if necessary
- And modify the Magento's command to use https in the admin site.

Dear @jota
This problem is resolved as per your instructions. We have spinned up a fresh new VM and have tried it on that instance. Found it to be working fine. Then reverted back the bitnami.conf file in the production environment to it`s original state from the newly created VM.
This case can be marked as resolved and may be colsed.
Thank you.
