Intermittent connection with UA while using VeloCloud's SD-WAN service.
The SD-WAN performs some kind of protocol detection which conflicts with the traffic that UA sends to both the CTC and the Data Center.
Bypass from the SD-WAN the CTC IPs, the Portal IPs and the IPs from the Data Centers that you are connecting to.
Cloud Traffic Controller (CTC) addresses:
199.19.250.203
199.116.168.203
Portal addresses:
199.19.250.192
199.116.168.192
You can find the IPs for the Data Centers in the following KB:
