Failed to Run Localhost because of Run Time Error

I'm getting runtime error whenever I run the localhost. Redis was running but it only loaded the homepage. After about 10 seconds, the server stopped and gave us this error.

`__connect_nonblock': Operation now in progress - connect(2) would block (IO::EINPROGRESSWaitWritable)

I was able to test successfully before, I don't know why it's not working now.
Can someone please help out? Thank You!

Here are a few steps you can take to troubleshoot this issue:

Restart the server and Redis: Sometimes, simply restarting the server and Redis can resolve connection issues.
Check if Redis is running correctly: Run the following command in your terminal to check if Redis is running properly:

redis-cli ping

If Redis is running, you should see a response of PONG. If not, start Redis with the redis-server command.

Verify your configuration: Ensure your application is correctly configured to connect to Redis, including the correct hostname, port, and any authentication details (if required).

Check for port conflicts: Make sure that Redis is running on a port that is not being used by another service. By default, Redis runs on port 6379. You can also configure Redis to run on a different port if necessary. Edit the redis.conf file and change the port directive to the desired value.

Test network connectivity: Use tools like ping and telnet to check if there are any network issues between your server and Redis.
