Hello everyone! I want to share a situation that happened to me the other day. By the way, I have been using the ISPConfig3 for the last few years and have never encountered any problems. However, a few days ago it was necessary to set up a powerful server in terms of hardware and inexpensive in terms of cost. For a long time I used the services of the French provider OVH, but they recommended switching to Hetzner. Having rented a Cloud "CCX53" - 32vCPU, 128GB memory and 600GB disk, on Debian 12 installed, I tried to configure the ISPConfig3. The hostpanel was so slow that I thought there was a problem with the cloud. After which I decided to rent a dedicated server "AX162-R" - AMD EPYС 9454P (48 Core Genoa), 256GB DDR5 ECC memory and 2x1.92 TB disks. However, the problem with severe server slowdowns has not gone away. I tried reinstalling ISPConfig3 several times on Debian11 and Ubuntu 24.04, but also to no avail. The server refused to work quickly. The only thing I can say is that when the database was disabled, the sites started working and opening. Does anyone know why ISP refuses to work on Hetzner servers? Thanks.
First, I removed your catchy and wrong headline. Then, ISPConfig is not slow on Hetzner at all. I have all my systems at Hetzner and they all are very fast. So what you are reporting here is neither an issue with ISPConfig, Hetzner, or the combination of the two. You verified this yourself already, you exchanged the system from cloud to a dedicated server and both feel slow and you have been using ISPConfug before, so you know that neither the Hetzner server nor ISPConfig is the cause of your issue. And hetzner base images are way better and cleaner than the ones from OVH btw. Also, reinstalling will not help in such a situation, as you can not find out why the system is slow when you do that. Back to your problem, as we know now that your issue is not that ISPConfig refuses to work at hetzner, as you wrongly claimed, you should now check what the real issue of your problem is by checking which apps cause the load on your system. You say you disabled a database and it started working then, I assume you talk about the database of a website? Then your likely issue is a DOS attack on that specific website. You should check the access.log of the site.
And as you claim ISPConfig GUI was so slow, it might because by your desktop and not ISPConfig or Hetzner. Something like a DNS issue or a filtering software or settings on your Desktop PC. Also, why do you use an outdated OS like Debian 11 and not the current one, Debian 12?
I completely stopped the MariaDB database on the server and only then did the static sites start to open.
Ok, but then you can not access ISPConfig of course, as it won't work without a database. You must check why your system was slow by checking which processes cause this. as I mentioned, a DOS attack is a likely cause of such a problem.
Also, it might be that you configured special settings for PHP or MariaDB for some of the sites on the old system and you might not have done that on the new system.
There were no DDoS attacks. The question is, why did I configure ISPconfig on OVH servers and everything works fine, but when I tried to configure it on Hetzner, everything slowed down terribly?
You do not know why your system was slow, but you know it was not a DOS? Sorry, but you can not know that, as you still do not know what slows down your system. And when disabling the DB helps, then a DOS or similar attack is more than likely. The points you wrongly claimed have been sorted out already, so its time you start checking what the cause is. Because it's neither related to Hetzner, nor OVH, nor ISPConfig, it's as if I would claim my PC is slower since I purchase electricity from another company or claim servers installed on Friday are slower than servers from Tuesday.... As you can see, the kind of claims you made do not make sense and will not help you find the cause of your issue. I have quite a few ISPConfig systems at Hetzner, all of them are fast (dedicated and cloud). I managed systems for customers at OVH in the past; the OVH systems were always slower compared to Hetzner systems in the same price range, and the setup was not very clean at OVH. Now you might want to go back to your system and check which process is slowing down your system and which website causes this.
