应用服务器的pgadmin连接问题

Question

I am using pgadmin 4.2.0 but when I open it to use, it shows the following error

The application server could not be contacted.

I installed and uninstalled the Postgres and pgadmin using brew many times but facing the same issue.

Thanks in advance,

Answer 1

A solution could be the usage of this docker image:

Answer 2

you can fix that problem with the following terminal command:

mv $HOME/.pgadmin $HOME/.pgadmin_backup

The problem is caused by the contents of the folder "~/.pgadmin". This folder may contain corrupt files or files of an incompatible pgadmin version. The above command renames the folder so that there are no more annoying, old data. If necessary, old configurations can be reconstructed from the old folder.
