Hi,

I am trying to configure openproject (opensource) in Amazon AWS EC2 instance.
I followed the manual installation guide of OpenProject and everything went well, without issues.

Now, when I am tyring to access OpenProject from EC2 ip address and trying to create a new account, it is jumping to 500:error page.

For more information I checked the production.log file and here are the logs:

All the values in configuration.yml file is as per indicated in Manual Installation Guide.

Please help me out on what is the exact issue occurring, and anything else I need to add in configuration file to resolve this issue.

…
Thanks & Regards,
