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

• 🧵 database connection

• 🧵 Postgres Database Connection Error

• 🧵 Issue with the database connection.

• 🧵 Slow deployment issue in production

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

hey, did you test any potential mismatch between qa/prod related to SSL settings? (e.g., sslmode=require vs verify-full or missing CA)

when you say fails to connect from local env - do you have any logs? is it a connection refusal, is it timing out, etc?

In local i am getting connection timeout issue

In local i am getting connection timeout issue

We deployed to production yesterday, and everything was working fine last night during our sanity testing. However, since this morning, none of the APIs are responding—they take a long time to process and eventually time out.

To investigate, we first tried connecting the production database from the local environment, but the connection also timed out. Interestingly, the production database works fine when accessed via pgAdmin.

Next, we checked the QA environment, and it’s working as expected. The QA database connection from local is also successful.

Additionally, I created a duplicate of the production backend server but configured it to use the QA database, and it worked fine as well.

Based on these tests, the most likely cause seems to be an issue with the production database, which is a PostgreSQL instance deployed on Railway. We’re continuing to debug to identify the exact root cause.

did you try to just redeploy your latest commits on prod for the services? im potentially thinking it's that (if you duplicated the backend services and it worked fine)

Yes i redeployed the server but it didn't work.

i think youd likely have to troubleshoot exactly the difference between qa/prod. if you happen to run:

psql "$PROD_DATABASE_URL" -c "select inet_server_addr(), inet_server_port(), now();"

and it winds up timing out, its a network/DNS issue. if it returns, something else on the client side is different. you can also look at whether your db has connection pool exhaustion, so you can run something like

SELECT state, count(*) FROM pg_stat_activity GROUP BY 1;.

and either fix pooling or raise it (if it's near max connections).

check the I/O, see if you have any queries causing the db to be slow as well select * from pg_stat_bgwriter; if they are, youd need to vacum the tables.

if it happens to be a network/DNS issue, you can proxy through a TCP port if it's through a public network (if it's already there, id disable it and re-configure it), or force IPv4 with hostaddr by doing something like:

dig +short prod-db.internal.railway

psql "postgresql://postgres:mysecret@prod-db.internal.railway:5432/mydb?sslmode=require&hostaddr=123.45.67.89"

I noticed another issue: on Railway, within the database architecture view, the database itself isn’t connecting — it just keeps showing a loading spinner.

I checked connection issue and it shows:
current_connections: 21
max_connections: 500

Statistics related to the background writer:
"checkpoints_timed","checkpoints_req","checkpoint_write_time","checkpoint_sync_time","buffers_checkpoint","buffers_clean","maxwritten_clean","buffers_backend","buffers_backend_fsync","buffers_alloc","stats_reset" "30","1","186537","199","1869","0","0","4","0","7088","2025-10-31 06:56:22.187314+00"

The above results are good i guess.

New thing:
I am able to connect prod DB via PGAdmin and connecting string through terminal

The loading spinner in Railway's dashboard is the smoking gun - Railway's health check is failing to reach your database. This breaks private network routing, which is why your backend services timeout but external tools (pgAdmin, terminal) work fine.

Quick fix: Switch your backend to use DATABASE_PUBLIC_URL instead of DATABASE_PRIVATE_URL temporarily, then restart the database service from Railway dashboard. The health check should recover and private networking will come back.

If that doesn't work, check if you have a custom healthcheck configured that's pointing to the wrong port or path.

Hello!
That was a bug that should have been fixed as of now.
