Issue while zoom integration with self hosted docker mattermost on aws ec2

Hi All,

am exploring to use mattermost with zoom integration, followed guide at Connect Zoom to Mattermost - Mattermost documentation , but after several tries am getting error on matermost docker log as

mattermost-1 | {“timestamp”:“2025-08-01 02:50:09.876 Z”,“level”:“warn”,“msg”:“failed to get the user”,“caller”:“app/plugin_api.go:1014”,“plugin_id”:“zoom”,“error”:"message: Click here to link your Zoom account.. error: 400 error returned while fetching zoom user. "} could someone please suggest how to debug this issue, is it plugin not able to access the zoom API ? i kept “Zoom URL:” and Zoom API URL: as blank…to get default values.

TIA
