Issues connecting to db2 cloud from jupyter notebook

Hi! I am doing the ibm data science course, and ibm wants me to connect to my db2 cloud. I found my credentials and put it in the premade %sql command, but i get an error as shows in the field “ln[20]”. Can you help?
ps. i exchanged my actual password and username fake ones after executing, so they are not actually suppose to be “username” and “password”
