How to Fix Slack Freezing During Connection Issues with Speedify

You Can Join Multiple Internet Connections Together - Like Starlink, Wi-Fi, 4G, 5G, and DSL - with Speedify, to Fix Slack Freezing

Slack is the popular, award-winning messaging and collaboration app. It serves teams as a modern alternative to email in the workplace. That is – until the moment Slack freezes and you have to reboot.

You can fix Slack freezing: join 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 freezing 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.

Speedify bonds any two connections into one — automatic failover, more speed, no dropped calls.

Why Slack Freezes and How to Fix It

When Slack freezes, it can be one of the following:

  • you do not have the latest version of the app / software. You should update that.
  • their servers go down. In this case, a simple check of the Slack status page can confirm.
  • you are experiencing slow or unreliable Internet.

The best way to fix Slack freezing is to look at 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 hiccup 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.

Slack has put together this troubleshooting guide you can check out to fix Slack freezing. 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.

Fix Slack Disconnecting with Speedify

Speedify is a bonding VPN that changes the way your computer or mobile device connects to the Internet. Instead of just using one connection, Speedify can combine 2 or more connections at the same time. This instantly increases your connection bandwidth and reliability and provides a better Slack experience. You’ll be able to get work done in any situation, even when traveling!

Speedify also monitors the quality of your Internet connections. When it detects that a signal is weak or that the network is too slow (remember public WiFi?), it will automatically and seamlessly reroute the data through the other working connection(s). And when the “original” connection is back online and reliable, it begins using it again  automatically. Say goodbye to Slack freezing!
