‘Connection Error: The Server aborted the connection’ error message is generated when launching Junos Pulse on iOS

This article describes the issue of the ‘Connection Error: The server aborted the connection’ error message being generated, when attempting to launch Junos Pulse an iOS device.

The following error message is generated, when attempting to launch Junos Pulse on an iOS device


From the User access logs, you can view the following message:

There is no VPN Tunneling Profile defined or the IP Pool has been exhausted and does not have any available IP addresses that can be assigned.

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.
