Any category with a slug that starts with a number returns a 404 if visited directly, but works find if navigating there from the homepage. If relevant, this is a discourse instance nested in a subdirectory `/forum`.
[https://austincodingacademy.com/forum/c/123-graduate-projects](https://austincodingacademy.com/forum/c/123-graduate-projects) =\> doesn’t work
[https://austincodingacademy.com/forum/](https://austincodingacademy.com/forum/) =\> click on Graduate Projects =\> works
Here is the relevant parts of my `app.yml`
```yaml
- replace:
global: true
filename: /etc/nginx/conf.d/discourse.conf
from: proxy_pass http://discourse;
to: |
rewrite ^\/(.*)$ /forum/$1 break;
proxy_pass http://discourse;
- replace:
filename: /etc/nginx/conf.d/discourse.conf
from: etag off;
to: |
etag off;
location /forum {
rewrite ^\/forum\/?(.*)$ /$1;
```
Any thoughts? Might this be related to [Slugs that start with numbers parsed as IDs](https://meta.discourse.org/t/slugs-that-start-with-numbers-parsed-as-ids/50258)?

The easiest workaround is to avoid leading numbers in your categories.
