Jira webhook throwing TLS Handhsake Error

Troubleshooting Command Line Interface
1

When making any changes within a specific project on Jira, Mattermost immediately spits out this error:

{“level”:“info”,“ts”:1548826292.1131835,“caller”:“http/server.go:1763”,“msg”:“http: TLS handshake error from xxx.xxx.xxx.xxx:61090: EOF”,“source”:“httpserver”}

curl -v --insecure "https://myurl/plugins/jira/../.../… --> works and returns fine.

Forward80to443 = True

But unfortunately, I’m receiving no messages to my channel.

Please help.
