Admin Web is not responding on version 26.3.1

When following the instructions in the Readme

# get the last docker-compose-bot file
curl -o docker-compose-bot.yml https://raw.githubusercontent.com/theopenconversationkit/tock-docker/master/docker-compose-bot.yml
# get the script to start mongo in replicaset mode
mkdir -p scripts && curl -o scripts/setup.sh https://raw.githubusercontent.com/theopenconversationkit/tock-docker/master/scripts/setup.sh && chmod +x scripts/setup.sh
# get the last tag
curl -o .env https://raw.githubusercontent.com/theopenconversationkit/tock-docker/master/.env
# launch the stack
docker-compose -f docker-compose-bot.yml up

I just have to had this on mongo services as there is a memory issue or something related on Fedora

mongo:
    environment:
      - GLIBC_TUNABLES=glibc.pthread.rseq=1

Then, the stack starts successfully but when I open the Tock Studio homepage on http://localhost the page cannot be accessed. I am not seeing any errors in Docker services.

What’s strange is that when using CURL, a content is returned.

Do you have any ideas what's going wrong ?

Start by reviewing the README instructions and the downloaded docker-compose-bot.yml, scripts/setup.sh, and .env files. Run the stack on Fedora, compare the browser result at http://localhost with the content returned by curl, and inspect the Docker services; done means the Tock Studio homepage loads successfully without the extra environment workaround.
