How to Fix “Connection Refused” in Redis (2026 Guide) The Short Answer To fix the “Connection Refused” error in Redis, adjust the timeout configuration to ensure your client can establish a connection within the allotted time frame, typically by setting timeout to a value between 5-30 seconds. For advanced users, you can use the redis-cli command with the --timeout option, such as redis-cli --timeout 10. Why This Error Happens Reason 1: The most common cause of the “Connection Refused” error in Redis is a misconfigured timeout setting, where the client is not waiting long enough for the server to respond, resulting in a socket error after a default timeout of 1-2 seconds. Reason 2: An edge case cause is when the Redis server is experiencing high load or network latency, causing the server to take longer than expected to respond, exceeding the client’s timeout threshold. Impact: The “Connection Refused” error manifests as a socket error, preventing your application from interacting with the Redis server, which can lead to data inconsistencies, errors, and downtime. Step-by-Step Solutions Method 1: The Quick Fix Go to redis.conf > timeout setting Set timeout to a value of 10 seconds (e.g., timeout 10) Restart the Redis server to apply the changes. Method 2: The Command Line/Advanced Fix You can use the redis-cli command with the CONFIG SET option to adjust the timeout setting: ...

How to Fix “Connection Refused” in Supabase (2026 Guide) The Short Answer To fix the “Connection Refused” error in Supabase, advanced users can try adjusting the Pooler configuration by setting the pool_timeout to 30 seconds and connection_limit to 50. This can be done by running the command supabase config set pool_timeout=30 and supabase config set connection_limit=50 in your terminal. Why This Error Happens Reason 1: The most common cause of the “Connection Refused” error in Supabase is a misconfigured Pooler, where the pool_timeout is set too low, causing connections to timeout before they can be established. For example, if the pool_timeout is set to 5 seconds, and the database takes 10 seconds to respond, the connection will be refused. Reason 2: An edge case cause of this error is when the connection_limit is set too low, causing the Pooler to run out of available connections. This can happen when there are a large number of concurrent requests to the database, such as during a traffic spike or when running a large batch job. Impact: The “Connection Refused” error can have a significant impact on database connection, causing delays, errors, and even crashes. In a real-world scenario, this can result in a 30% decrease in application performance, with an average response time increasing from 200ms to 500ms. Step-by-Step Solutions Method 1: The Quick Fix Go to Settings > Database > Connection Pooling Toggle Enable Connection Pooling to Off Refresh the page to apply the changes. This will disable connection pooling and allow Supabase to establish new connections on demand. Method 2: The Command Line/Advanced Fix To adjust the Pooler configuration, run the following commands in your terminal: ...
