No internet connection after Catalina upgrade

New day and I have good good news.

I received a response from KeepSolid VPN Unlimited:

"It seems like you have not uninstalled the application on your other system user on your Mac.

Please try to log in with other users to the system and check if VPN Unlimited is not uninstalled yet"

The recommendation was a little weird to me because I used to have only one system user (it is my personal laptop and no one else use it), and I created a 2nd admin user just for isolate this issue.

Even do, I restarted and tried to login using the Guest User, and I COULDN'T LOGIN: Guest User was asking for a password (Why?)

So, I login with my original system user, and then I switched to the Guest User. In this case I do was able to login.

After that was easy:

System Preferences -> Network

The VPN Unlimited was BLINKING, trying to connect (on and off) on the left pannel.

It was a kind of chasing to select it (It moved so fast from top to bottom), then I deleted, logouted of Guest User and DONE: Internet is back.

I assumed Guest user is DELETED every time a machine is restarted but not, for some reason VPN Unlimited was there in the Network Preferences, trying to get connected.

I'm happy, the problem went away and I learned something new. Thanks for your support and hopefully could help others.

Thanks Cåts but didn't work.

So far I tried:

• Turning Wi-Fi on and off
• Restarting my machine
• Connecting to a different network and to a phone using as a Hostpot
• Creating a new Location (under Preferences->Network)
• Deleting and adding Wi-Fi network (left pannel under Preferences->Network)
• Isolate issue, creating a new Admin User: Issue was temporary solved (Internet is lost time to time but still)
• I was looking on the Console view and found a very strange process many times:

Process: nesessionmanager

Message: NESMIKEv2VPNSession [Primary Tunnel: VPN Unlimited BDABB51A-7845-43E9-A633-6B05D7FBD5BC (Null)]

I used to have VPN Unlimited but it was uninstalled about 3 years ago. The app does not show under apps folder neither on Preferences->Network

Any idea?

Grant Bennet-Alder, in my original post I said my currect VPN (EndPoint Security) still get connected, even after Catalina Upgrade (with no internet connection?). That is weird. Btw, I uninstalled that VPN and the problem continues.

Hey Cåts, if you refers to reinstall the KeepSolid VPN Unlimited, I already tried but couldn't because instalation requires Internet connection (even using an instalation .dmg from other machine).

The link you mentioned, actually reinforce me to the issue is related with the VPN, thanks

Hi Grant Bennet-Alder

Nothing happens with 1.1.1.1 (no internet conection)

I wrote an email to KeepSolid VPN Unlimited and waiting their recommendations

Thanks Cåts

Actually KeepSolid VPN replied with the same recommendation as you (and did not work), so they forwarded my issue to their technical department. Hopefully they come with a solution.
