Connection closed to http://supervisor/core Loop

For months now I have had the problem that Node red installed on homassitant, at some point goes into a loop of connecting and disconnecting http://supervisor/core and I can’t make sense of the logs that homassistant gives me.

After a restart of node red everything works again without problems for an indefinite time between 1 day and a week

updates did not work, installing node red new also did not work

Does anyone have an idea what the problem could be or how I can further look for the problem?

Welcome to the forum @Der_TJ

Few here use HA, preferring to do everything in node red directly.
I suspect you will have to ask on an HA forum.

I already try that but also nothing

Can you copy/paste what you see in the logs please? Copy/paste the text, not screenshot. When pasting, use the </> button at the top of the forum entry window in order to stop the forum from interpreting it as markdown.
