Slow access to the server homepage/timeout during updates

Hello,
I've been having a problem for a while now that I can't seem to solve.
When I try to access the server's homepage via HTTP, there's no problem; it's instantaneous. However, with HTTPS, it takes at least ten seconds before I even get to the login prompt.
There's no problem launching the console (which points to HTTPS), but I occasionally get timeouts on the WUA side on certain clients (not always the same ones), with the error message "THttpClientSocket.OpenBind(wapt1.xxx.xxx.com:443): Is a server available on this address:port? [remoteip=] [#3 Not Found]".
There's nothing obvious in the Nginx and Wapt logs. Any idea what could be happening?
I have the impression that it started after the update from version 2.5 to 2.6.
Thank you
WAPT 2.6.1.17576
Debian 12 server
, creation machine Win 11 24h2

If the problem is related to https, I suppose it's due to missing flags on the CPU side.
You can send back the order result!

It would be interesting to see if the AES is emulated (which consumes power).
You can switch to host-type CPU to see if
always refers to aes

Indeed, the AES has disappeared, but that hasn't solved the problem.

This problem did not exist (I think) on version 2.5, but I don't remember changing anything on the VM/OS side during the migration to 2.6.
Perhaps there was a problem during the migration? Especially since I seem to remember seeing something strange with the certificate (a self-signed one) a few days ago when I was looking for the cause, but unfortunately I can't remember how or which command I used to see that strange thing.
I was thinking of generating a new certificate for testing purposes, but I couldn't find the procedure to follow.

Luckily, I remembered doing a Google search for this error, so I was able to find it in my history. The certificate is valid until 2033, but it says "CRL validation error on certificate."
I must have made a mistake during the migration; I've always had trouble understanding these certificate issues.

aes is indeed present
So that's not it.
One of the big changes that occurred between 2.5 and 2.6 is client certificate authentication.
I don't really see what could slow things down.

Okay, well, I won't bother with it any longer. Since Debian 13 is out, I'll back up the server and start with a clean install, hoping that will resolve the issue.
Two questions:
I'm starting to run out of space because of old Windows updates still on the server. If I don't transfer the /var/www/waptwua/ folder during the backup, will it clean things up? Will Wapt re-download what it needs?
The restore procedure mentions doing a standard installation, but is it necessary to run postconf.sh?
Especially since it needs to be restarted after importing the old data?

Okay, I haven't done a clean reinstall yet, but strangely enough, after updating the WAPT server yesterday, the problem disappeared
; no more slowness or timeouts.
We can close this topic!
