We have installed a self-hosted Gitlab Container registry on a separate server behind an Apache Proxy Server. It has its own domain with https enabled. The Gitlab server is on a different server with a different domain. The problem is when I try to push the image to the registry after successful login I am getting the below error:
docker push registry.gitlab.example.com/web/web-app:latest
The push refers to repository [registry.gitlab.example.com/web/web-app]
5f70bf18a086: Layer already exists

Also I noticed on registry server under v2 folder there is a directory with the name of the image and inside it has has many directories. I am not sure is it the complete image uploaded or few layers of it. However on the Gitlab interface under container registry I see nothing. During the push I also observed error logs on Apache proxy server as:

I followed all the troubleshooting available however could not fix this issue. Any help would be highly appreciated. Thanks
