I have followed the below link and added authentication for Bitnami Magento 2.3.2 development site which is in AWS Lightsail.
I have created htpasswd and magento_users using,
cd /opt/bitnami apache2/bin/htpasswd -cb apache2/magento_users USERNAME PASSWORD```
Also I have added the below code in /opt/bitnami/apps/magento/conf/httpd-app.conf
... AuthType Basic AuthName MyAuthName AuthUserFile "/opt/bitnami/apache2/magento_users" Require valid-user ... = 2.3> # Require all granted...
After I have restarted the apache and flushed the cache, It asked for username and password when loading dev frontend. When I provide credentials, it end up getting error as,
Error 503 Backend fetch failed Backend fetch failed Guru Meditation: XID: 393256 Varnish cache server
I can’t see anything related to this in Apache error_log.
Can anyone please help me out to fix this issue.
