<![CDATA[XO-6 Cannot connect to server over Unifi SD-WAN, XO-5 works well]]>I have two sites in the SD-WAN (created over two UDM-pro's). XO-5 works well, and has for months. When I upgraded to XO-6, I started having server connection issues. It doesn't appear to be the 30s issue that was patched in April, as I will physically lose connection (pages won't load). I did some research, and fed the issue into Claude, and it seems to point to an architecture change between the keep-alive format (SSE in V6, vs Websockets in V5).

Does this make sense? Has anyone encountered this before? Thoughts/suggestions? I can stay on V5 with no issue, but was hoping to learn V6 more.

Thanks!

Your SD-WAN is cutting the feed?
