Failing pg_restore of a small DB

Question

Hi! Newbish question, I'm trying to restore a postgresql dump to railway, the documentation says that the domain will look something like `containers-us-west-15.railway.app` but the domain in my dashboard looks like `mainline.proxy.rlwy.net` and the attempted restoration always times out (error below). It's a very small dump so I can't see any reason for this, am I missing something?

```pg_restore: error: connection to server at "mainline.proxy.rlwy.net" (66.33.22.234), port 5432 failed: Operation timed out
    Is the server running on that host and accepting TCP/IP connections?
```
