Connection Established but stuck in "Connecting" State


I have installed Viscosity in a Windows 10 environment without error and imported my connections. However, for all my connections, when I try to login the connection got successfully (and I'm able to join the servers in my vpn) but the connection status keep the "connecting" state. But the worst is when I try to disconnect from the VPN: it switch from "connecting" state to "disconnecting" and keep this state forever making me unable to join again the same VPN (until I kill viscosity and start it again).

Could you help me to solve it? below the connection log (some data are anonymized).

Hi guidomi,

Could you please post a copy of your configuration as exported from Viscosity. You may wish to email this to us instead as this forum is public.

Hi Eric,

I think/hope you need only the config.conf file and not the certifiacate/key files. Below you will find it (anonymized of course)

Hi guidomi,

Could you please check the Event Viewer for any errors relating to Viscosity or Viscosity Service - ... nt-viewer/

Hi Eric,

In the event viewer, after I started my vpn connection, I get periodially the 3 errors below under security stuff. Nothing, instead, under application.



Could you please edit your connection, go to Advanced and add the following line on a new line:

#viscosity dns simultaneous

Save the connection and then try to connect again. Please let us know if the connection completes.

Hi Eric,

Nothing is changed with this modify.
Hi Guidomi,

I'm afraid we're a little stumped. Could you please boot into safe mode and see if the problem is still present there with no other applications or services running?

Hi Guidomi,

Viscosity v1.6.6 has been released, could you please try updating to this to see if the problem still persists as well.

Hi Eric,

I already tried to upgrade it to the new version but I get the same issue. I also tryied the safe mode with network, but it that mode the viscosity service is unable to start.

Do you have any idea about what it could be?
