XOA SocketError: Other side Closed

Vagrantin

Hello
I'm also experiencing the same issue on my XCP-ng / XOA .
My XCP-ng host time to time disappear from XOA.

Here is the error I have in journalctl

Here is the node version:

node -v
v20.18.3

When I looked for XOA version, found it difficult to find it.
So I had in fact to go back to XO lite to find that I'm on 2025.11.

As for XCP-ng i'm on 8.3.0 .

My XOA is hosted on top of XCP-ng on the same machine.

Any advice to understand the cause of this issue are welcome.

Best.
