Nowadays, more than 1 billion messages are sent via Slack weekly! It’s a great way to conduct business as long as it’s working properly. But, for many users Slack seems to have connection issues.
The reason for your Slack connection issues can originate from their side (servers) or from your Internet. If it's your connection, you can fix your Slack connection issues: combine your main Internet connection with another Internet source like a Starlink or DSL, 4G, 5G. Whether at home, work, or on-the-go, Speedify works with all live streaming software and social platforms to get you faster, more reliable and secure Internet.
In this article we'll show you how you can fix Slack connection issues to get more productive at work.
Quick answer
Should you have a backup 4G, 5G, Starlink, or cable internet connection?
Yes — every internet connection goes down, including Starlink, which drops for ~34 minutes a day on average. A backup connection from a different provider means one outage never takes you fully offline. The most common options are a 4G/5G cellular hotspot, a cable or DSL line, or a second satellite dish.

Works anywhere. Just a SIM or hotspot — no installation needed.

Why Does Slack Have Connection Issues?
As mentioned above, when Slack doesn’t work, it can be one of the following:
- their servers are down. In this case, a simple check of the Slack status page can confirm.
- you are experiencing connectivity problems.
The most common cause of Slack connection issues is actually the network you’re connected to. When you have a slow or unreliable Internet connection, your Slack isn’t able to work properly. Sometimes, you may not even realize that you have a Slack connection problem until you try and use the service.
Most often it’s people working while commuting that encounter these issues. That’s because they get stuck on bad WiFi networks. Their laptops and mobile devices don’t know when to switch to another hotspot or connection. If your WiFi connection has a momentary blip or your cellular connection fluctuates, some of the flow of those packets gets interrupted. It can take a few moments for the data to catch up.
This results in Slack messages not sending and calls where the audio cuts in and out, where the video lags, and where the audio and video don’t sync properly.
How to fix? Slack has put together this troubleshooting guide you can check out to fix your connection issues. Solutions mostly go around clearing your cache and reloading Slack. But wait… there’s a better way to fix Slack connection issues related to your Internet.
