It looks better, i think…

Yes, 401 means wrong credentials and there’s no timeout anymore.
Please recheck the username and password.
The username and password are correct. Even if I change the administrator’s password, the message remains the same.
Does the password have to be entered without the " " ?
No, the " " are needed.
But is it only used with the lowercase placeholder?
If your password is
Secret123
then the command is:
curl -k -s -o /dev/null -w '%{http_code} %{time_total}\n' \
-X POST https://192.168.154.20/users-admin/ad.xxx.com/api/login \
-H 'Content-Type: application/json' \
-d '{"username":"Administrator","password":"Secret123"}'
Sorry, my mistake… Now it looks good.

Lets have a break for the moment. My wife need my help.
Authentication works but it takes about 13 seconds. Usually it should be much faster.
And that’s exactly the point I don’t understand. This NS8 instance ran without any problems for more than two years. Aside from regular updates to the OS and the installed apps, nothing else happened.
What surprises me, though, is the fact that the error occurs even on a brand-new system. In that case, however, the actual installation and initial setup didn’t work the first time either—it only succeeded on the second try.
Really strange, I tried to reproduce the issue, I used the same ISO and installation procedure and don’t get the error. I used “host” as CPU for the Proxmox VM.
I think that the initial setup error can be ignored but the Samba timeout is odd. I assume that you get similar errors with LAM on the fresh installation.
Is there maybe high load on your servers?
You can check on the nodes page or for example with uptime:
[root@node1 ~]# uptime
18:08:13 up 7 days, 1:37, 2 users, load average: 0.09, 0.19, 0.27
Output of uptime looks normal for me.
20:17:18 up 10:09, 1 user, load average: 0.23, 0.21, 0.29
Did you use Rocky 9.8 as an ISO?
Yes, the load is ok.
I used the Rocky 9.4 minimal ISO to simulate your scenario.
It’s really hot here in the Rhine-Main area right now. And it’s even hotter here in the apartment. I’m going to give Alma Linux a try over the next few days. Or maybe Debian. Let’s see if that works better. Thanks for your kind help…
Interesting that the network side (DNS, port 636) responds instantly but a single login takes 12–13 seconds — that points to something internal to the VM stalling the auth, not a network/DNS issue.
Two things worth checking (Note: this diagnostic suggestion was drafted with AI assistance.):
1. Disk I/O
Samba writes to sam.ldb/secrets.tdb on every auth, so slow storage can cause exactly this kind of delay. While reproducing the slow login, in another shell:
vmstat -t 1
Check the wa (iowait) and st (CPU steal) columns during the curl test. Also useful (optional):
dnf install sysstat
iostat -x 1
Look at %util/await on the disk backing the VM.
2. CPU type / AES-NI
@mrmarkuz mentioned using host as CPU type in Proxmox for the working repro. If your VM uses a different CPU type without AES-NI passthrough, Kerberos crypto (aes256-cts-hmac-sha1-96 in your logs) falls back to slow software AES, which could also explain a ~12s login. Check:
grep aes /proc/cpuinfo
and confirm the VM’s CPU type setting in Proxmox.
Since this ran fine for two years and now shows both an odd Kerberos “protocol unreachable → ok” retry and a slow response, something environmental (storage or CPU config) may have changed rather than NS8 itself — the numbers above should confirm or rule that out.
Output of vmstat -t 1:

For both VMs (the primary node and the worker node), the CPU is set to “Host.”
There are clues of a slow disk behavior. Please repeat the login + iostat test with
iostat -x 1 -t | tee iostat.log
Then paste here iostat.log contents. It’s important to fetch I/O data during the curl login test.
Then run as root also the disk-performance (fio) NS8 tool, during non-working hours, to draw a clear profile of the device used by samba1. It’s a one-minute heavy disk job.
cd ~samba1
disk-performance -o fio.txt
Please paste here also fio.txt contents.
