Hi there,

It sounds like that you might not be using the correct tag naming convention. You need to make sure that the tag follows this convention:

registry.digitalocean.com/<my-registry>/<my-image>

Here is a quick overview on how to do this:

Use the registry login command to authenticate Docker with your registry:
```
doctl registry login
```
Copy
Use the docker tag command to tag your image with the fully qualified destination path:
```
docker tag <my-image> registry.digitalocean.com/<my-registry>/<my-image>
```
Copy

Use the docker push command to upload your image:

docker push registry.digitalocean.com/<my-registry>/<my-image>

Let me know how it goes!

Best,

Bobby
