FortiClient VPN bytes received 0

Hi Francesco,

Looks strange and not sure why it is behaving like that. Anyways on a side note, I will also try these.

- Check with older versions of Forticlient.

- Check windows routing table on your machine. This might gives you some clue.

- Check Windows updates and also try to update ethernet adapter drivers.

regards,

Sheikh

We are having the same problem, but it's not related to a windows update. It does the problem at random on our computers. We are having 1 or two case per day. Usually, waiting about 10 minutes before reconnecting solves the problem.

We have no idea why it's doing that. We don't have access to the VPN network when the received bytes are at 0. It's not a DNS problem because we can't ping IPs either. Our Forticlient VPN is version 7.0.7.0345 but we've been having the same issue with previous versions.

Note : we are on Windows 10 22H2, not 11

Would be interested in a solution.

Thanks!

Exact sam problem "FortiClient VPN 7.0.7.0345" and "Windows 11 Pro 22H2 22621.1265"

El problema esta en la actualización de Windows KB2693643

I don't have installed KB2693643, but I have the same problem, Bytes Received 0 and the session is disconnected. Any idea what could cause the problem?

Same problem here ever since we started using FortiVPN. Intermittent problem, I might have the problem to day on my device and tomorrow my device will work fine, only to have the problem again next week.  While I have the problem, others are able to connect.  While I can connect, someone else will have the problem. On most days, everyone can connect.  But this is still a problem - my answer to users can't be "wait until later and try again".  It has noting to do with routes, etc... I/P v4 isn't loaded upon connection, although IP v6 is loaded.

The issue you're experiencing, where FortiClient VPN isn't receiving any bytes despite the correct VPN configuration, can be due to a few different factors. Here are some steps you can try to troubleshoot this issue:

1. **Check Network Connection:** Ensure that your internet connection is stable and working properly. Sometimes, intermittent network issues can interfere with VPN connections.

2. **Reinstall FortiClient:** Uninstall and reinstall the FortiClient VPN. This could help in case there are any issues with the installation.

3. **Check VPN Settings:** Although you've mentioned that the VPN configuration is correct, it's worth double-checking the settings. Ensure that the IP address, username, password, and any other required parameters are correct.

4. **Try a Different Network:** If possible, try connecting to the VPN from a different network. This can help determine if the issue is related to your network.

5. **Check for Software Conflicts:** Some software might conflict with the VPN connection. You've mentioned that you've tried disabling the firewall, antivirus, Teams, OneDrive, etc. Consider if there are any other software applications that might be interfering.

6. **Check VPN Logs:** FortiClient should generate logs that could give clues as to why the connection isn't working. You can check these logs for any error messages.

7. **Update FortiClient:** If an update is available for FortiClient, consider updating to the latest version.

8. **Check with IT Support or VPN Administrator:** If you're connecting to a customer's VPN, it might be worth checking with their IT support or the VPN administrator to see if they can provide any insight.

If none of these steps resolve the issue, you might want to contact Fortinet support for further assistance.

Hi !

Had the same problem on Ubuntu.

- bytes recieved 0

- I could disconnect but never reconnect afterward

I used NetworkManager CLI to list all connections `nmcli con`

A dozen "vnp00xxx" connections were open while Forticlient was disconnected.

I closed all "vpn00xxx" connections with `nmcli con down vpn00xxx`

Then I could connect again and receive bytes :)

I have a similar issue..
I changed my internet provider (try tethering to my mobile phone internet), and the issue resolved.

Im facing also same issue. I tried this much options but still same issue..

I changed local internet for client system.

I tried the old to latest version for forticlient.

I tried in other pc also..
