This error (“Error: request returned Internal Server Error for API route and version,”) typically comes up during interactions with Docker or Docker Compose APIs. In this quick troubleshooting guide, we will look into the causes behind this issue and explore effective troubleshooting steps to resolve it.
Common Causes
Now let’s discuss some of the main causes of this error.
API Version Mismatch
API version mismatches can often cause errors when the client and server communicate using different Docker API versions. Docker Desktop, Docker Compose, and other related tools depend on specific API versions to operate correctly. To resolve this issue, ensure that both the client (your local environment) and the server (the Docker engine) are using the same API version. You may need to upgrade or downgrade one or both to achieve compatibility. Additionally, regularly check for updates and maintain consistency across your Docker tools to prevent similar issues in the future.
Storage Issues
Storage issues can lead to unexpected errors, particularly if there is insufficient disk space for Docker to operate. Docker requires adequate disk space to store images, containers, volumes, and other data. To address this problem, check your available disk space and free up storage if necessary. It may also be beneficial to allocate more space specifically for Docker to ensure smoother operation and prevent similar issues in the future. Regular maintenance and monitoring of your storage resources can help avoid these problems.
Configuration Problems
Configuration problems can arise from incorrect settings in your Docker or Docker Compose configuration files, often triggered by typos, missing properties, or misconfigured services. These issues can cause various errors that disrupt your workflow. To resolve this, review your docker-compose.yml and Docker configuration files carefully. Verify that all service definitions are correct and ensure they align with your intended setup. Regularly checking and validating your configurations can prevent these errors and ensure smooth operation.
Troubleshooting Steps
Option 1: Check API Versions
First, check the API versions to ensure consistency. Both your local Docker client (e.g., Docker Desktop) and the Docker server (whether running on your host or in a container) must use the same API version. Mismatched versions can lead to unexpected errors. If necessary, upgrade or downgrade Docker Desktop to match the server’s version. You can find the API version in the Docker Desktop settings or by running docker version in your terminal.
Step 1: Check Docker Client and Server Versions

Mismatched versions can lead to unexpected errors. If necessary, upgrade or downgrade Docker Desktop to match the server’s version. You can find the API version in the Docker Desktop settings or by running docker version in your terminal.
Step 1: Check Docker Client and Server Versions
docker version
Step 2: Upgrade Docker Desktop (If Necessary)
brew upgrade --cask docker
Step 3: Downgrade Docker Desktop (If Necessary)
brew install --cask docker@20.10.5
Step 4: Verify the new Docker version
docker version
Ensure that the client and server API versions match.
Option 2: Check Storage Space
Next, if Option 1 does not work, inspect your storage space. Check the available disk space on your system using commands like df -h on Linux/macOS or Get-PSDrive on Windows. Free up space by identifying and removing large files or unnecessary data, such as old images, containers, and volumes. If space remains limited, consider allocating additional storage to Docker to ensure smooth operation.
Step 1: Check Available Disk Space
df -h
Step 2: Identify Large Files and Unnecessary Data
du -sh /* 2>/dev/null | sort -rh | head -n 10
Step 3: Remove Unused Docker Resources
# Remove all stopped containers
docker container prune -f
# Remove all unused images
docker image prune -a -f
# Remove all unused networks
docker network prune -f
# Remove all unused volumes
docker volume prune -f
Option 3: Configuration Checks
Lastly, as a final resort, perform configuration checks. Review your docker-compose.yml file to verify that service definitions, including containers, networks, and volumes, are correctly defined. Look for typos, missing properties, or misconfigurations. Additionally, inspect Docker’s global configuration, such as /etc/docker/daemon.json or Docker Desktop settings, to ensure the settings align with your intended setup. Regularly checking and validating your configurations can prevent many common issues.
Step 1: Open and Review docker-compose.yml
nano docker-compose.yml
Key Points to Verify in the File:
- Services: Ensure each service (e.g.,
web,db) is correctly defined with appropriate images, ports, volumes, and networks. - Volumes: Check that volumes are correctly declared and referenced.
- Networks: Verify that network configurations are consistent and correctly referenced by the services.
Step 2: Check Docker’s Global Configuration
sudo cat /etc/docker/daemon.json
Key Points to Verify
- Storage Driver: Ensure the storage driver (
overlay2,aufs, etc.) matches your requirements. - Log Level: Adjust log levels (
debug,info,warn,error,fatal) as needed. - Insecure Registries: Verify any insecure registries are correctly listed.
- Registry Mirrors: Ensure registry mirrors are correctly configured.
- Bridge IP (bip): Check the custom subnet IP configuration.
