Hi,

I'm pretty new to proxmox and have installed proxmox with a zfs raid 1 (SSD & nvme) on a lenovo m910q:

Code:
CPU(s)
 
8 x Intel(R) Core(TM) i7-6700T CPU @ 2.80GHz (1 Socket)
Kernel Version
 
Linux 6.2.16-19-pve #1 SMP PREEMPT_DYNAMIC PMX 6.2.16-19 (2023-10-24T12:07Z)
PVE Manager Version
 
pve-manager/8.0.9/fd1a0ae1b385cdcd

PVE is connected via 1GBit with my network:

I'm running a Debian 12 standard container to host grafana and influxdb 1.x only with IPv4 configured:

I have updated the container with apt update and upgrade of course. Unfortunately, I have sporadic timeouts with the grafana ui. When these timeouts occurred, I tried to ping the host to see if it is reachable or not. At the time of the Grafana UI timeout, the grafana host (201) is not reachable.

I'm also running pihole on pve and have never seen timeouts. Also pve is running very well.

First I thought maybe there is a general issue with the pve host/ machine, but obviously it isnt.

I also saw a post in this forum that kernel 6.5 can lead to a performance impact. I havent updated the kernel (is still on 6.2.

In the beginning, I have added the IPv6 address to the lxc container (retrieved if from my fritz box) but have removed it (as seen in the screenshot above).

Does anyone have an idea how to find out why there are sporadic network timeouts?

Thank you in advance!
