This is clearly an issue that is yet t be resolved with OpenVPN and macOS. This has been ongoing for years with macOS and OpenVPN regarding of Intel or Apple silicon.

The only solution I've had success with, albeit annoying and should NOT need to be done, is disabling and reenabling the Wi-Fi connection. I have not tried this with a wired connection so I can't speak to what happens in that scenario.

Regardless, the OpenVPN developers have zero interest in fixing this issue with macOS. However, it's a free application, so how much can we really complain?

@IndyCarSuperFan

I can tell you that wired connection suffers the same fate too.

Would you be kind to share what you are using as your openvpn router?

Thanks

I have this same issue and it's really annoying.

I find the easiest way to address this is reboot my Mac but that is equally annoying. This doesn't happen on my Windows laptop or my iPhone at least which is nice.

I am running Sonoma 14.2.1 and have OpenVPN setup on my Asus RT-AX82U running firmware 3.0.0.4.388_24231-gbc11d13

My setup is

TUN
UDP
AES-256-GCM
SHA 512
Compression - Disabled
TLS
HMAC Auth - Disabled
VPN Subnet 10.8.0.0 (Wifi network is 192.168.50.x)
Push LAN to clients - Enabled
Direct clients to redirect internet traffic - Enabled


Previously I had OpenVPN loaded on my Synology NAS and I never recall having this issue. I may go back to that setup and see if works better. I was just having problems enabling cert auth in that setup. That setup was easier in the Asus router so I switched to this setup.

Having the same issue. It's weird because sometimes operating browser works but some online apps don't.

Solution (windows 10):

Network and internet settings > Change adapter settings > Right click on Ethernet adapter > disable > enable

This seems to clear what ever is blocking some internet traffic, not perfect but faster than rebooting PC.

Another solution I found worked, was running a separate VPN after Openvpn disconnected (nord for example). This seems to clear the issue as well.

Having similar type of issue.

When I login into openvpn for first time it works properly and also net is properly work.
But when I disconnect openvpn and again reconnect to OpneVPN I lost internet.

Anyone has idea about it?

I have been struggling with this for a few years but I may have figured it out.

I exported an OpenVPN config from a Netgear router and that config file does not contain the certs or the key inside, it instead points to separate files that contain that info.

so if you open the ovpn file with a text editor instead of <ca> CERTIFICATE TEXT </ca> it would read ca ca.crt
The same for cert and key. You will need to make three new files, two with the .crt filetypes and one with a .key filetype.

So far this has allowed me to connect and disconnect openvpn running from a TPLink router without losing internet.
