      family: 0,
      retryStrategy: (times) => {
        // reconnect after
        return Math.min(times * 50, 2000);
      },
    };

nixpacks or dockerfile?

TurboFarmer9000•7mo ago

nixpacks with the sleep command in the package.json start command

Brody•7mo ago

according to the redis service settings, is that host correct?

TurboFarmer9000•7mo ago

redis-cache-staging.railway.internal Should i have the http infront ?

Brody•7mo ago

redis does not use http

TurboFarmer9000•7mo ago
