Rudder

Hello,

When the web gui is used to display the page of any node (https://rudder.example.com/rudder/secure/nodeManager/node/716931d4-82ce-43b5-af58-5250a1fd28f5/...), a central turning waiting wheel is turning for a long time, before a popup is showing "The server cannot be contacted at this time".

Clicking OK on this popup gives back control to a classical use.

In Firefox dev tools, I see that amongst the sent queries, one is falling into timeout :
https://rudder.example.com/rudder/lift/ajax/F92342300211914LZXU-10/
with the answer:

NS_BINDING_ABORTED

This behaviour is affecting every node. It appeared maybe around mid-September (I'm writing that, knowing that I'm strictly following every upgrade)

One thing I noticed was that when trying to reach https://rudder.example.com/rudder/secure/nodeManager/node/716931d4-82ce-43b5-af58-5250a1fd28f5/..., I'm also seeing in /var/log/daemon.log this message :

rudder-relayd[505]: ERROR report{queue_id=node_uuid_123456789}: rudder_relayd::processing::reporting: refused: report from
 "716931d4-82ce-43b5-af58-5250a1fd28f5", unknown id

/var/log/rudder/webapp/2024_12_17.stderrout.log is also showing :

WARN  net.liftweb.http.LiftRules - Unmapped Lift-like parameter seen in request [/lift/ajax/F92342300211914LZXU-10/]: F923423002129US4ZQL

and /var/log/rudder/apache2/error.log is showing:

What may I check further? what could be solved?

Thank you.
