Testcontainers not able to connect to Docker in Spring Boot project

I’m working on a Spring Boot project using Testcontainers, but I’m facing an issue where Testcontainers is unable to connect to Docker.

Error:
Testcontainers is failing to connect to your local Docker daemon.

What I’ve tried so far:

- Verified Docker daemon is running

- Restarted Docker and system

- Updated environment variables (DOCKER_HOST, etc.)

- Restarted Testcontainers setup

Environment:

- OS: Windows

- Java version: 17

- Spring Boot version: 3.0.0

- Testcontainers version: 1.19.7

- Docker version: 29.3.1

Question:

What could be causing Testcontainers to fail connecting to Docker, and what should I check next?

Any help would be appreciated.
