proxmox failing to connect to samba share with error NT_STATUS_LOGON_FAILURE (500)

[fdavidg]

Hello,

I am running Proxmox version 8.3.3 at this time. Starting this past Monday I can no longer connect to my NAS via a Samba share thru my TrueNAS server. I can connect to this share from a Windows 10 machine with no problem. I am at a total loss on how to solve this problem. I have a cluster running pve and pve2 that has been running flawlessly since before September 2024. Now all of a sudden I have totally lost the ability to run my VMs.
i dont recall doing any updates before having the problem.How can I check the last kenel update date and time? Im running proxmox VE 8.3.3 and if any logs are required ill try to respond asap.
I have noticed in the DataCenter Summary that pve is reporting a server address of 10.12.34.31 rather than 192.168.1.250 I think it should be.
I have seen mention of reverting the kernel by Kingneutron in May 2024: "Try booting back to a previous kernel version, 6.8 kernel is apparently a clusterb0mb for lots of ppl", but I have no idea if this applies or even how to proceed to do so.
I would appreciate any and help to resolve this issue!
Thank you in advance.

Hello fdavidg!

You can check the contents of /var/log/apt/history.log.

I have seen mention of reverting the kernel by Kingneutron in May 2024: "Try booting back to a previous kernel version, 6.8 kernel is apparently a clusterb0mb for lots of ppl", but I have no idea if this applies or even how to proceed to do so.

When doing a major kernel update (e.g. 6.8 to 6.11), it is possible for the network interface to get renamed. Or otherwise it can also happen that a network card is no longer detected (e.g. due to incompatible drivers).

Some thoughts:

1. What is the output of ip a?
2. What is the output of lspci?
3. Do you see any error messages related to the network card or drivers in dmesg?

I have noticed in the DataCenter Summary that pve is reporting a server address of 10.12.34.31 rather than 192.168.1.250 I think it should be.

Please check and (if necessary) adapt, the network configuration, either under Datacenter -> NODE_NAME -> Network, or by editing /etc/network/interfaces (see Apply Network Changes).
