Still having trouble?
We can reach slack.com, so if you can't, it's likely one of these.
Hard-refresh and clear your cache
Force a fresh copy with Ctrl + Shift +R (Cmd + Shift +R on Mac). If the page still won't load, clear your browser's cache and cookies for slack.com, then try again.
Flush your DNS cache
- Windows:
ipconfig /flushdns - macOS:
sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder - Linux:
sudo resolvectl flush-caches
Switching to a public resolver like Cloudflare (1.1.1.1) or Google (8.8.8.8) can also help.
Try a different network or device
Switch from Wi-Fi to mobile data (or vice-versa), or open the site on your phone. If it loads elsewhere, the problem is local to your network — not slack.com.
Disable VPN, proxy and extensions
Ad-blockers, VPNs and some browser extensions can block requests. Turn them off, or open slack.com in a private/incognito window to test with a clean profile.
