Re: Unable to Connect to Server Error Help

Thanks for the feedback!

I tried inputting “localhost” and “127.0.0.1” into pgadmin’s name field for
setting up a new server, but got an error message that read “connection to
the local server has been lost.”

Any help on what I should try next would be appreciated.
