Unable to change default admin password nexus

I just installed nexus v 3.59, running in a docker container. I was able to retrieve the default admin password, and then the system forces you to change the default. When ever I try to enter any kind of password, I just get a triangle with a warning in the upper right of the screen, but there is not text on the warning. I have tried several different passwords, no matter what I try I get that warning and can not continue with the setup. Any suggestions?

Check your anti-virus, browser extensions or (reverse) proxy servers to see whether they are interfering with the requests.
