Kong Manager Network Error

[aureuslim]

I have 2 Kong setup with Kong Manager enabled, 1 Kong OSS in Docker, and 1 Kong Enterprise Free Version in Ubuntu.

Both my Kong Manager works when using HTTP://localhost.com, however both has the same issue of having Network Error under the Workspaces overview.

The configurations that I have edited in kong.conf are as follows:
admin_listen = 0.0.0.0:8001 reuseport backlog=16384, 0.0.0.0:8444 http2 ssl reuseport backlog=16384
admin_gui_listen = 0.0.0.0:8002, 0.0.0.0:8445 ssl
admin_gui_url = http://localhost:8002/
admin_gui_path = /
admin_gui_api_url = http://localhost:8002/

This is the error displayed on Google Chrome Console:

GET http://localhost:8002//default/kong net::ERR_CONNECTION_REFUSED
GET http://localhost:8002//workspaces?size=15&sort_by=created_at&counter=true net::ERR_CONNECTION_REFUSED

Can anyone please let me know if I missed out on any other important configurations or did I edit any of these configurations wrongly?

I can provide more details as to what I have done in the setup, or whatever necessary.

@sumimakito , could you take a look at this?

Hello @aureuslim,

admin_gui_api_url sets the base URL for Admin API requests, which would be http://localhost:8001 according to admin_listen = 0.0.0.0:8001 in your case.

Meanwhile, we recommend omitting the trailing slash while setting URLs such as admin_gui_api_url and admin_gui_url.

You may try to update your configuration with the following changes:

- admin_gui_api_url = http://localhost:8002/
+ admin_gui_api_url = http://localhost:8001
- admin_gui_url = http://localhost:8002/
+ admin_gui_url = http://localhost:8002

I hope this will be helpful. Please don't hesitate to comment if the issue continues.
