The connection to Jira is very slow. The requests take up to 5minutes. We have a AWS load-balancer in between:
Please do a curl request to your Jira from the host-machine on which you have the pi-planning server installed. Does that work? It could be an network issue. (curl -D- -u <jira-username>:<jira-password> -X GET -H "Content-Type: application/json" https://<url-to-jira>/rest/api/2/issue/<some-issue-key>)
Reach out to service@rentouch.ch if you have challenges with your Webhook configuration.
