Big Problem on Influxdb2

hello. I have a big trouble. I have had an error in my local network, and I have assigned the same IP of the influxdb 2 server to a new computer (two computers with the same IP). After changing the IP to the new computer, I can’t get into influxdb2. I can’t access the data. It’s like everything has been erased.

When I try to push data from node-red into influxdb I get this error:
“Error: 401 on {“code”:“unauthorized”,“message”:“unauthorized access”}”
I have influxdb2 installed in an image in PROXMOX. I have replaced the image with a backup, and the result is the same. This is very extrange.
