Hi Nauman, I hope you are using junos pulse for SSL VPN connection because we don't have junos puls e clients for UAC dot1x authentication on mobile devices. Thebelow knowledge base link deals with 'Connection Error: The Server aborted the connection' error message is generated when launching Junos Pulse on iOS. This is same as your issue. This KB link also has teh cause ans solution. http://kb.pulsesecure.net/InfoCenter/index?page=content&id=KB23046 Check if there is a VPN Tunneling Connection Profile created and mapped to the user Role, to which the user belongs. The VPN Tunneling Connection Profile on IVE can be checked under Users > Resource Policies > VPN Tunneling > VPN Tunneling Connection Profiles : If there is no profile created for the role, click New Profile and provide either the valid IP address pool or the DHCP server and map the profile to the correct User Role. When the SA Series device receives a client request to start a session, it assigns an IP address to the client based on the IP address policies, which are defined either through DHCP or the IP address pool. If you do not have any VPN Tunneling Connection Profiles configured, the Junos Pulse client will not be able to obtain any IP address; subsequently the Connection Error: The server aborted the connection error message will be generated. For more information on requirements to assign an IP address, refer to KB22889 Hope this Helps. Note: If I have answered your questions, you could mark this post as accepted solution, that way it could help others as well. Kudo will be a bonus thanks! Regards, Kannan
