I'm using VSCode Remote-SSH to connect to a cluster, which works normally. But approx. every few minutes I get prompted to re-enter my password, after which it works again for a few minutes. My only issue is the constant re-prompting.
Here is the Remote-SSH log of when the re-prompt occurs at [10:59:03] until I re-enter it.:

Can someone decypher this log and find out what is causing the repeated password prompts?
I tried the 'Kill VS Code Server on Host` option without effect. Also I tried in a local terminal to ssh-copy ssh key to find a way to avoid having to enter a password at all, but it seems that the cluster doesnt allow it (I am still prompted every time I connect).
I also tried enabling remoteSSH.useFlock without success.
