As per marketplace version listing at https://marketplace.atlassian.com/apps/1220099/jira-server-for-slack-official/version-history

Version 2.0.21 • Released 2021-12-06 • Supported By Atlassian • Free • Atlassian Closed-Source

Version 2.0.20 was mistakenly released with an option that forces a specific HTTP protocol when calling Slack that effectively breaks communications. This version removes such option.

Updating of an add-on should solve your problem.
