Webhook from jiracloud not working with ssl/let's encrypt

[Pantelis Karamolegkos]

We have set up a webhook from jira cloud to a custom application;

our application is containerized and behind nginx reverse proxy that uses Let's Encrypt certificates;

The webhook seems to work over http but not over https.

nginx logs indicate no specific error;

The webhook also works over https when it is manually triggered from postman;

any suggestions?
