Describe the problem*

I have tried several iterations of deploying a fresh DO droplet. Each time I am now prompted with the following error when I try to access Inventree:

Steps to Reproduce

1. Click on the Deploy to Digital Icon logo.
2. Click on the Create Inventree Droplet icon.
3. Create a Basic type droplet, CPU type Regular
4. Create Droplet
5. Go to project, click on Get Started

6. Click on Quick Access to Inventree
   

7. The usual login prompt is missing, goes straight to server error page

You need to specify the INVENTREE_SITE_URL setting, as per the docs:

• https://docs.inventree.org/en/stable/start/config/?h=inventree_site_url#basic-options
• https://docs.inventree.org/en/stable/start/config/#server-access

@SchrodingersGat thank you for looking at this. This was not necessary the first time I deployed the droplet months ago. I am further confused because the URL and credentials are already provided in the message of the day when I open the SSH terminal.

Please understand that I have no experience with Linux and I can barely manage interacting with the console. I do my best to follow instructions and steps others have shared, but I don't really know what I am doing. Maybe Inventree just isn't for me.

I tried executing root@inventree0168onubuntu2004-s-1vcpu-1gb-nyc2-01:~# inventree config:set INVENTREE_SITE_URL=http://162.243.234.188 but I am still getting the internal server error.

Thanks again for your assistance.

This was not necessary the first time I deployed the droplet months ago.

As you can see in our 0.17.0 release notes under "breaking changes" (and also on the release blog) there is a change to the underlying django code which requires an adjustment to your setup.
