This article describes an issue with upgrading a VA-DTE & PSA-V to 9.1R4 and above where end users are unable to connect and the generic error message of "Network Error".
Problem or Goal
When using the VA-DTE or PSA-V appliance with 1 CPU core configured, end users will fail to connect with the error message of:
Network error. (Error: 1115)
If the device is rolled back to 9.1R3 and below, end user will be able to connect to the device again.
Cause
