Browser asks for authentication when I mount localhost config and database folders

[ghost]

My docker image uses an ubuntu Xenial base image with java, I installed orientdb to /opt/orientdb in the container thus formed, after which I mounted a database and config folder from my localhost to the container. I mapped the 2480 port to the studio and then run localhost:2480 to access the studio. I can see the databases I had created before, but when I login using the credentials I had set before, which are present in the config file, I get a popup in the browser which asks me to authenticate. I don't know what credentials to add there, even the root login doesn't work. Below is the error on the console.

Exception `54384099` in storage `plocal:/opt/orientdb/databases/OperatingEvents`: 2.2.33 (build 77584cd6827f647cf4aa231cf27bd6f10bc04e2c, branch 2.2.x)

Might be your OS (possibly not your browser) asking for permission to share the local folder with docker. In my case It was exactly like that.
