I have internet connection but I get the not connecting error in some apps and I can't use the apps

Question

I have internet connection but I get the not connecting error in some apps and I can't use the apps

I have 13" MacBook Pro 2018. I use Movaje last version

My problem is that some apps don’t open after sleep because probabyl they cannot access the internet but i have internet. For example Whatsapp App, Microsoft Teams, Slack said that “The computer is not connected to the internet” but I had already connected. If I try to open these apps with a browser, they open properly. Its applications cannot access internet.

The problem disappears when I restart the computer.

I tried some suggestions like change DNS or change Network Preferences Location etc. but my problem continues.

Please determine if the same problems occur in "Safe Mode": Use safe mode to isolate issues with your Mac .

Needless to say, if you are using, or have used at any time in the past, any non-Apple "anti-virus", "cleaning", or "Internet security" products including "banking security", anything at all in that broad category of utterly useless garbage, don't. A lot of things won't work if you do.

I understand. Safe Mode is merely a troubleshooting aid. It helps to know the problem does not occur in that mode. Please restart your Mac normally if you haven't already.

In an effort to further isolate the cause consider Using EtreCheck. Post its report in a reply to this Discussion. Those instructions explain how to do that. Because its output will this site's 5000 character limit for text entry you need to use "sheet of paper" icon below the text entry field.

Antivirus software: Apple and Kaspersky

That'll do it. Uninstall the "Kaspersky" garbage in strict accordance with its instructions. Rule 1 of Macs is don't install junk.

This computer has configuration profiles installed.

Find out what they are. Provided you own and control that Mac no Profiles should be installed, in which case its presence should be questioned. Installed Profiles can be found in System Preferences. Identify that Profile; post a screenshot of that pane if need be.

To capture a screenshot read Take screenshots or screen recordings on Mac - Apple Support. To include it in a reply, use the icon just to the right of the "sheet of paper" icon.

By default, screenshots are saved to the Desktop.

I started it in safe mode and have been using it for 4 hours. There is no problem for now. For the past 3 months, I have used a bitdefender and its VPN service. I removed it, but the problem persisted. How do I solve this problem. I can't use the computer in safe mode forever lol.

I deleted the Kaspersky properly and it is no longer in the report. There is one internet profile installed in the system. It is eduroam. In order to connect to the network at universities, we have to install this "eduroam" profile. Could it be related to this?

Maybe it was because of Kaspersky, I'll try it for a while and I'll update here.

I have been trying for 2 days and there is no problem. Thank you so much! Mac was freeze occasionally. That problem also disappeared. As a result of my research for 2 days, I learned why I should not install a virus program on a Mac.
