Thanks for using Bitnami! I checked the files of the
bnsupport and in your logs appears the following error:
[Sat Aug 01 22:49:50.766808 2020] [authz_core:error] [pid 4562:tid 140689337726720] [client 127.0.0.1:53302] AH01630: client denied by server configuration: /opt/bitnami/apps/magento/htdocs/app/etc/config.php
Could you run the next command and check if resolve the issue?
sudo chown -R daemon:daemon /opt/bitnami/apps/magento/htdocs
I hope that helps you.
