Connection with Enterprise Manager cannot be established: PR_END_OF_FILE_ERROR

[62mkv]

I am trying to follow https://github.com/oracle/docker-images/blob/main/OracleDatabase/SingleInstance/README.md#user-content-running-oracle-database-18c-express-edition-in-a-container

and when I try to connect to https://localhost:5500/em, I get

Secure Connection Failed

An error occurred during a connection to localhost:5500. PR_END_OF_FILE_ERROR

error (FF browser) (the port, obviously, is mapped to the appropriate container)

When I try to debug this failure using openssl (under Win10), this is what I get:

>openssl s_client -connect localhost:5500 -state

not sure, if it's something with my PC or with the image.

Here's what I do to reproduce:

• clone https://github.com/oracle/docker-images
• cd to OracleDatabase\SingleInstance\dockerfiles\18.4.0\ (this is chosen because it doesn't require to manually download Oracle binaries)
• run the following:

docker build -t oracle/database:18.4.0-xe -f Dockerfile.xe .

• once image is built, use this .cmd to run it:

docker run --name test-oracle-1 ^
--shm-size=1g ^
-p 1521:1521 ^
-p 5500:5500 ^
-e ORACLE_PWD=oracle ^
-v <PATH-to-mapped-data-folder>:/opt/oracle/oradata ^
oracle/database:18.4.0-xe

running this on Windows 10 x64, Docker Desktop 3.6.0 with WSL2 containers
