FortiClient VPN bytes received 0

Hi, I'm using FortiClient VPN for conneticting to a customer's VPN but I can't receive any bytes:

Same username and password on other PC work and every username and password on my PC don't work.

I tried disabling/closing: firewall, antivirus, teams, onedrive, ...

I have the default settings of Windows 11 and I'm using FortiClient 7.0.7.0345.

VPN configuration is correct.

 

Could someone help me please?

 

Thanks in advance

Francesco

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.

Hi Sheikh,

 

- Where I can find older versions?

- Same routing table of my collegues

- Windows is updated and even the ethernet adapter driver

 

Same problem, 0 bytes received.

 

Any other ideas?

Mhm, do you get any infomration from the FortiClient Log?

 

I had this error, when i set the log level on "troubleshooting":

 

error sslvpn FortiSslvpn: 19616: Error find interface for local_gwy 651c0a0a

 

When i googled it, the only reason for that was another vpn installed on the client but thats not the case.

Hi Steffen,

 

I don't have any error in the log file, just I don't received any bytes.
