Description:
Hello, I have been running an n8n project on Railway for about 4 months without issues. Suddenly, my Redis service started crashing and the project no longer works.

Details:

• Service: Redis (used as queue for n8n with EXECUTIONS_MODE=queue)

• Postgres is configured and working fine

• Redis was running stable until a few days ago, no changes were made

• After redeploy, service still crashes and shows CRASHED in Railway dashboard

• Logs only show that the Redis connection fails or is not reachable

Environment Variables (without secrets):

DB_TYPE="postgresdb"
DB_POSTGRESDB_HOST="${{Postgres.PGHOST}}"
DB_POSTGRESDB_PORT="${{Postgres.PGPORT}}"
DB_POSTGRESDB_USER="${{Postgres.POSTGRES_USER}}"
DB_POSTGRESDB_PASSWORD="${{Postgres.POSTGRES_PASSWORD}}"
DB_POSTGRESDB_DATABASE="${{Postgres.POSTGRES_DB}}"

EXECUTIONS_MODE="queue"
QUEUE_BULL_REDIS_HOST="${{Redis.REDISHOST}}"
QUEUE_BULL_REDIS_PORT="${{Redis.REDISPORT}}"
QUEUE_BULL_REDIS_USERNAME="${{Redis.REDISUSER}}"
QUEUE_BULL_REDIS_PASSWORD="${{Redis.REDIS_PASSWORD}}"

Problem:

• Redis service shows as CRASHED in production

• n8n can’t connect to Redis anymore (getaddrinfo ENOTFOUND or connection refused errors)

• Even after redeploy, the crash persists

Question:
Could this be related to a recent Railway change, Redis config update, or do I need to adjust my variables?
Any guidance would be really helpful
