• I can reproduce this issue, or for intermittent issues I've included trigger, frequency, and timing details below.
• I removed or anonymized sensitive data from logs, screenshots, and configuration.

Yes, this worked before

Regression details

The invite behind this redirect has been replaced before after it expired (#2905, #3401, #3674).

Summary

The Slack link used across the repo and docs, https://docs.netbird.io/slack-url, points to a Slack shared invite that no longer lets new members join the workspace.

Current behavior

https://docs.netbird.io/slack-url redirects (307) to https://join.slack.com/t/netbirdio/shared_invite/zt-43j76787p-otf3d0nMcJHAQYx46H3jsg, which ends at netbirdio.slack.com/join/shared_invite/.... Slack shows "This link is no longer active", so new members cannot join.

Expected behavior

The link opens a working invite to the NetBird Slack workspace.

Steps to reproduce

1. Open https://docs.netbird.io/slack-url in a browser, not signed in to the NetBird workspace.
2. Try to join.

Impact

README, CONTRIBUTING.md and AGENTS.md all point contributors to Slack for questions, so new contributors currently have no way in.

Additional context

The redirect lives in netbirdio/docs (next.config.mjs). Slack shared invites expire after a set time or number of uses, so an invite with no expiry, or a reminder to rotate it, would stop this recurring.
