Hi everyone,

I’m running into an issue with my n8n instance on Railway, where it suddenly lost connection to PostgreSQL after working fine for several hours.

Here’s the context:

• Setup: n8n hosted on Railway with PostgreSQL as the database (deployed using the default template).

• What happened: The connection worked perfectly for hours, but after I made some changes to my workflow (no configuration changes), it stopped connecting to PostgreSQL. I haven’t altered any settings like environment variables or database config.

• Additional detail: I was working on two browser tabs at the time, editing the same workflow. Could this have caused a conflict?

• Symptoms: n8n can’t connect to the database anymore, and I’m not sure why since it was stable before the workflow edits.

I’ve checked the basics:

• Environment variables (e.g., DB_TYPE=postgresdb, DB_POSTGRESDB_HOST, etc.) seem correct in Railway.

• No obvious errors in the workflow changes that should affect the DB connection (just typical node updates).

• Haven’t dug deep into logs yet—looking for advice on what to check there.

Has anyone seen this before?

Could the two browser tabs have caused a session conflict, or might this be a Railway/PostgreSQL hiccup?

Any tips on what to look for in the logs or steps to fix this would be appreciated!

Thanks in advance!
