Cant connect to instance

Hello,
I would like to use neo4j aura to share my DB with other people.
Everything is created fine, I export it from my local to aura . it is marked running (see photo) but when I try to connect to my instance I get an error message (see photo) do you have any idea what could cause this problem?
And if it's because my port 7687 is blocked, how can I change the access port?
Thank you and have a nice day
