Unknown error when sending a message on VKontakte

Until VK launched a new design, users had no errors when sending messages. At the moment, some users cannot send messages to others either from their phone or PC. In this article we will look at:

  • Reasons why messages don't arrive
  • How to eliminate them
  • What to do if nothing helps

First, let's tell you what this error is. Problems with sending occur when you have written a message, click on the send button, but instead of displaying the sent text, you see a pop-up window. Or a red icon with an exclamation mark appears next to your message. Such errors can occur when sending not only text messages, but also voice messages. Let's look at what can be done to eliminate them.

VKontakte error that occurs when sending messages to VKontakte

The first thing you need to do is restart VK and check the Wi-Fi is working. Click on the F5 button on your open page. Try sending the message again. If the download is very slow, restart Wi-Fi. Unplug the router for a few minutes, then plug it in again.

To find out for sure what the reason for the error is, try sending a message from a phone with a cellular connection connected, but without Wi-Fi. You can connect data transfer on your iPhone in the settings section.

If the message is sent correctly, then there is a problem with your PC or internet signal. If nothing happens either, it means that VK has a problem. You cannot influence it in any way; in this case, you should send a request to the support service and wait for a response. We wrote in this article how to make a request and how long to wait for a response:
