Problems to access to Relational Database course

Hi everyone. I am trying to enter into the Relational Database course but when I try to enter the process of loading remote enviroment frezzes in “Starting virtual server” step.
I have tried to enter with Chrome and with Edge, but nor one neather the other work.
Could somebody help me?

try refreshing the page multiple times and try opening a different course with in the Relational Database course and if it opens then get back to the course you want and try opening it.if none worked for you the last choice would be to go to codeally and delete the container with the course that is problematic to start,unfortunately you have to start the course from the begining.
