Hey there! We've found the following might help you get unblocked faster:

• 🧵 public domain not accessible
• 🧵 Custom domain redirects to railway public domain
• 🧵 The custom domain I registered under Public Networking has suddenly disappeared.
• 🧵 Can’t reach Next.js service from other containers using internal URL (only works with public URL)

If you find the answer from one of these, please let us know by solving the thread!

i'm just using express.js as my back end and I want it to connect to a mySQL database and I want to access the database through the url provided from railway

Hey, can you please elaborate on the crashing part? Connecting to your MySQL database can be done by reading the referenced DATABASE_URL environment/service variable.
