Hi Thor,
The stacktrace ("java.net.UnknownHostException: .slack.com: Name or service not
known ") seems to indicate a bad host name or url?

Betreff: ALPN callback dropped: SPDY and HTTP/2 are disabled. Is alpn-boot on
the boot class path?
Hello,
While attempting to integrate the Slack Plugin, I keep the above error. Checked
issues for this plugin on Github and JIRA but haven't found any open issues.
Decided to try posting here first before reporting.
Here is the full output of Jenkins Log:
