Grafana Add-on plots not visible after migrating HA

Hi,

I’ve just migrated from Supervised HA to HAOS on Proxmox VM. Home Assistant works fine but Grafana. After opening Grafana plot don`t appear.
In grafana log i see that it is attached to old host IP. Which config should i change?

logger=data-proxy-log userId=1 orgId=1 uname=admin path=/api/datasources/proxy/uid/NBwjSgN7z/query remote_addr=193.16.255.71 referer="https://my.external.adress/api/hassio_ingress/-gs2-5YBeO_SKrLv_ORCFFsTZKle_lcwmLS9t9ZSOOg/d/I8QDYfH7z/energy-today?orgId=1&refresh=5s" t=2023-09-24T20:48:42.334771636+02:00 level=error msg="Proxy request failed" err="dial tcp 192.168.1.236:8086: connect: no route to host"

this part is crucial ‘:err="dial tcp 192.168.1.236:8086: connect: no route to host’
