SSL VPN - client won't re-connect unless I re-install the Sophos Connect app

You need to have enough local rights to add and remove ip routes.

User is local Admin. Also tried running Sophos Connect Client as administrator. Is that what you mean by enough rights?

Hi Aaron Berger Regarding the error "The error Object already exists"  mostly only occurs if the system already has routes. Please check by entering route print in CMD and see if the route is already there or not on the same interface or any other interfaces of the system. If there's a route already there, there may be a chance that there are two different networks with the same IP subnet. Once you've taken care of that, you should not see the error while connecting SSL VPN.

I checked the routes before and after making the connection. Definitely no route for XG125 network in the list (192.168.0.X or the VPN IP range). This is what show in ipv4 route table: 

Hi Vishal,

that's what I thought, too. Maybe a route already exists and has to be removed manually before installing again.

Hello Aaron,

can you show the routing table after you tried establishing the connection?

Here's the route print during a successful connection:

Here's the route print during a non-successful connection:

Also, here's a route print with no connection attempt and Sophos app closed:

Is there another VPN software installed? For example fortinet or barracuda? Check if there is any other software and uninstall it - then reinstall Sophos and try again.

No other VPN software is currently installed. About 2yrs ago we did use Sophos Netextender on this device, but that has been completely removed.
