I am using kUbuntu 18.04(bionic) on my local machine and I installed postgresql11 and pgadmin4 step by step from this guide https://wiki.postgresql.org/wiki/Apt. And when i start pgAdmin4 firefox gives me this message:
Unauthorized
The server could not verify that you are authorized to access the URL requested. You either supplied the wrong credentials (e.g. a bad password), or your browser doesn't understand how to supply the credentials required.
Can someone tell me what I did wrong or what else should I configure
