I'm using the last version of the "OpenVPN Connect" for mac and I'm having some issues. Once connected to an OpenVPN server (server running from Asus GTX-10000 router) successfully, after disconnecting from it, the whole internet access of my mac (Mac mini M2 pro) is not working anymore. In order to recover the Internet connection I have to turn off the WiFi and/or ethernet and turn them back on. Could you please help me with this issue? Thanks!! Fred

Hello, It's possible you have conflicting routes. Do you know what subnets you have locally on your network where the mac is, and the subnets that the VPN server is pushing? If not, the client side logs would at least show what the server is pushing. It can be the case that because the remote and local subnets are the same, things end up getting broken. This can be resolved by ensuring the subnets are not the same. Kind regards, Johan

Thanks Johan !! Could you please tell me how I could be sure that the subnets are not the same. BTY, this issue is happening only on my Macs, when I'm using the same app from my iPhone (using the my same internet connection), I don't have this issue. Fred

I'm also facing the same issue as fkarausch2@gmail.com On my mac, I will lost connection to the internet once I disconnected from OpenVPN server. With my Andriod phone I can connect and disconnect without any issue. What could be the issue?

good news and bad news. After removing the application, re-configured my VPN server on the Asus router and exporting the new ovpn file config. everything started to work as expected (the issue that was loosening internet after disconnecting is gone!!!!) :D :D :D :D BUT :? :? :? :o :o :o now the connection is"painfully" slow, even connecting using the same connection at home (testing new VPN server from my same home connection) the speed is suffering a lot (~70% slower) Could somebody please help me with this !!!

to give you some info about my Open VPN server: Using: Interface Type: TUN Protocol:UDP Respond to DNS No Encryption cipher: AES-128-CBC HMAC Authentication: SHA 384 Compression: Adaptive Authentication Mode: TLS Extra HMAC Authentication: Disable VPN Subnet/Netmask: 10.8.0.0/255.255.255.0 ( my internal sub net 198.168.1.0/255.255.255.0) Push LAN to Clients: Yes Direct clients to redirect internet trafic; Yes Manage Client-Specific Options: Yes Allow Client n Client: Yes Thanks !!!

I am having the exact same issue. When disconnecting from the VPN, my internet doesn't work. Using the terminal to ping Google, I get the response [i]ping: sendto: No route to host[/i]. If I turn my WiFi off then on, everything works again. This also affects other users who use the same application and config file. Here is the ovpn config file I use, downloaded from AWS and with important details [b]#--REDACTED--[/b]: [code]client dev tun proto udp remote #--REDACTED-- dhcp-option DNS #--REDACTED-- remote-random-hostname resolv-retry infinite nobind persist-key persist-tun remote-cert-tls server cipher AES-256-GCM verb 3 #--REDACTED-- reneg-sec 0 redirect-gateway def1[/code]

Been waiting for a good solution but seems that only the 3 of us are facing this issue and no one seems to help. :-(

I'm having this issue on my MacBook (M1) as well. I'm having to remove plist files and basically having to reset my WiFi (forget the network, etc). Basically what is in this link: https://apple.stackexchange.com/questions/284581/wipe-all-wifi-settings-from-macbook I can connect to other wifi networks without an issue. I can log out as my user and in as an Admin and connect to the same wifi without a problem. Once I connect to OpenVPN to my office network, and it disconnects, my WiFi is basically dead. It will say it's connected, but the bandwidth is completely choked down to kbs. I just started to have this experience in the last week. I've narrowed it to the OpenVPN client and something happening after a disconnect from that client. I saw this post. So, I don't have a solution, but thought I'd post what I know so far. Thanks

Quick update: Turning Wifi Off, then On again did seem to clear something. This worked to restore my WiFi with normal speeds. Lot faster than resetting. Found that from another VPN client help guide: https://www.expressvpn.com/support/troubleshooting/mac-internet-disconnected-vpn/

UPDATE: I have an eero wifi mesh and turned on WPA3 in the labs (under Discover, eero Labs Beta - Activate WPA3 slider to on). This made my WiFi work again. I'll monitor this, but this may be the trick. Macbook Apple M1 Pro - Ventura 13.2.1 Narrowed my VPN client out as I seemed to have issues when my device went to sleep regardless of connecting to VPN.

Suffering from same problem with OpenVPN 2.6.5. TP-Link AX3000 as VPN server. Added data-ciphers for compatability. Subscribing to the thread for a solution.

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.

manushi

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.
