Database connection randomly fails after months of working fine - Dashboard gets stuck on "Database Connection"

Question

Hi everyone,

I'm experiencing a recurring issue with my PostgreSQL database on Railway and I'd like to understand what's happening.

The problem:

My database has been working perfectly for months

Suddenly, without any changes from my side, the connection fails

- In the Railway dashboard, the "Database Connection: We are unable to connect to the database via SSH." widget  keeps reloading, displays the SSH error, and reloads again... and so on

My deployed application also stops responding because it can't reach the database

After some time (5 MIN), it started work again on its own

What I've ruled out:

1. It's not an SSH issue (I'm not using SSH)
2. My environment variables haven't changed
3. The database service appears to be "online" in the dashboard
4. Other users have reported identical symptoms (I've seen several posts about the postgres.railway.internal private network hanging while localhost works fine), But the ticket related to this was marked as completed.

What I've trie:

1. Restarting the PostgreSQL service It worked after I redeployed Postgres, but it took quite a while.
2. Redeploying my application (sometimes works)

My questions:

1. Is this a known issue with Railway's internal private network? 
* although, I tried to connect to Postgres via the public network using DBeaver, but I couldn't connect either.
2. Why does the dashboard's "Database Connection" get stuck when this happens?
3. Is there any configuration I should check to prevent this?

Does Railway have an official status page for these intermittent connectivity issues?

My current configuration:

- DATABASE_PRIVATE_URL="postgresql://${{POSTGRES_USER}}:${{POSTGRES_PASSWORD}}@${{RAILWAY_PRIVATE_DOMAIN}}:5432/${{POSTGRES_DB}}"
- DATABASE_URL="postgresql://${{POSTGRES_USER}}:${{POSTGRES_PASSWORD}}@${{RAILWAY_PRIVATE_DOMAIN}}:${{RAILWAY_TCP_PROXY_PORT}}/${{POSTGRES_DB}}"
- NO_TS_TUNE="true"
- PGDATA="/var/lib/postgresql/data/pgdata"
- PGDATABASE="${{POSTGRES_DB}}"
- PGHOST="${{RAILWAY_PRIVATE_DOMAIN}}"
- PGPASSWORD="${{POSTGRES_PASSWORD}}"
- PGPORT="${{RAILWAY_TCP_PROXY_PORT}}"
- PGUSER="${{POSTGRES_USER}}"
- POSTGRES_DB="railway"
- POSTGRES_PASSWORD="****"
- POSTGRES_USER="****"
- RAILWAY_RUN_UID="0"
- SSL_CERT_DAYS="820"

Any insights would be greatly appreciated.

Thanks in advance.
