I’ve my Mattermost setup in Google Cloud Platform. When I tried to test my webhook connection from Gitlab (local server), there is some error message like below, captured from “gitlab-ctl tail” command:
OpenSSL::SSL::SSLError (SSL_connect returned=1 errno=0 state=error: certificate verify failed):
execute' app/models/hooks/service_hook.rb:23:in execute’
execute' app/models/service.rb:96:in test’
I’m using Letsencrypt for my Mattermost setup, Mattermost seems working fine but the webhook Notification just not working.
Is it something wrong with my SSL Certificate? I’ve no idea on how to troubleshoot this issue as I’m new to Gitlab and Mattermost.
Please help, very much appreciated.
