Common Mistakes to Avoid

1. Incorrect DNS Server Address

Reason: Entering the wrong DNS server address (e.g., typos or using an outdated address) will prevent Slack from connecting.
Solution: Double-check the DNS server address for accuracy and use a reliable source like your ISP's website or Google's public DNS.

2. Not Flushing the DNS Cache Completely

Reason: Failing to fully flush the DNS cache after changing DNS settings means your computer might still be using old, incorrect information.
Solution: After changing DNS settings, use the appropriate command (e.g., `ipconfig /flushdns` on Windows) to ensure a complete cache flush.

FAQs

Why would resetting my DNS server fix Slack?
Your computer uses a DNS server to translate website names (like slack.com) into IP addresses. If your DNS cache has outdated or incorrect information about Slack's servers, it can prevent you from connecting. Resetting the DNS cache forces your computer to fetch fresh information, resolving the connection problem.
What if resetting my DNS server doesn't fix the Slack issue?
If the problem persists after a DNS reset, the issue likely lies elsewhere. Try checking your internet connection, restarting your computer, or looking for Slack-side outages (check Slack's status page). If you're still having trouble, consider contacting Slack support.
