Description:

I installed pgadmin4 and then setup my nodejs app. While it is running I
cannot access the pgadmin4 web gui. I have setup a reverse proxy in my
nodejs app to localhost:5050 when i go to localhost/pgadmin4 since my routes
are blocking access. This does not work however and now I cant access
pgadmin4 with the nodejs app stopped. I have searched google and looked on
the bug tracker on github and cannot find any reference to this issue.

How do i access the web gui when i have a nodejs app setup with routes?
