Sometimes the Slack service may not work due to various problems. There are a couple of simple solutions that can work. Below we will tell you how to use Slack on iPhone, Mac, Android, PC, or in the browser, even when the service does not work.
Why is Slack Not Working on iPhone or MAC?
The reasons may be different. For example, Slack recently didn’t work because of DNS-related changes. To solve the problem, you had to ask your ISP to reset the DNS history for Slack.
At that time, the problems were solved quite quickly. We’ll tell you what to do if it ever happens again.
We are aware of connectivity issues related to DNS that are impacting a small sub set of users. This issue was caused by our own change and not related to any third-party DNS software and services. (1/3)

Solution 1: Change the DNS of your iPhone or Mac to use Slack
Slack can work if you switch to Google DNS.
Changing the DNS of your device is not very difficult. We have instructions on that. Just remember to use Google DNS.
The ways to change DNS settings on Android and PC are different, so you’ll have to look for separate instructions for them.
Solution 2: Use app 1.1.1.1 if Slack doesn’t work on iPhone or Mac
1.1.1.1 – an application for solving problems with DNS, and with its help the Slack service can be made to work. Best of all, you don’t have to change anything at your device’s settings.
Just download the 1.1.1.1 app to your iPhone, Mac, Android, or Windows PC and use it. When the 1.1.1.1 app is active, open the Slack app and it should work.
Additional Solutions
- Restart your device and Wi-Fi router.
- Switch to a different Wi-Fi network.
- Clear your browsing history if you use Slack in it.
- Uninstall the Slack app and reinstall it.
It’s important to note that as long as the service isn’t working, your messages don’t go anywhere. Once Slack is up and running, you’ll see all your incoming messages.
The messages won't be lost and, unless you've read them on another device, they'll still be marked unread when you're able to load the workspace. We appreciate how frustrating this is and we're very sorry. We may have a workaround — please write to feedback@slack.com.
