On appache I get the following error messages:

Do you ave any idea to solve my problem
Thanks!

I found nothing abnormal in the interfaces. Not knowing what to do, I completely reinstalled my virtual server, which restored the functioning of fog. Thank you for your answers

Please try:

rm -rf /etc/{php,apache}*
apt-get purge apache2* php7* php5*

Rerun through the installer.

It could also be that the FOG Server is simply too busy to respond before the timeout is over.

At work on 15 servers, and at home, I have systems set for Max Clients = 3 on all 1Gbps network buildings, and 1 for the 100Mbps buildings.

Thanks Tom, I will try and I will keep you informed.
Wayne, Everything worked correctly in this same configuration before

Thanks

After a new test, I still have this problem (see screenshot)

In the apache log file i have this :

It’s not the same problem but i don’t understand.
Thank you in advance

@Lombard RC-26 I tried to duplicate the issue at home on RC-26, and then RC-25 and could not duplicate it. Do you have any more information for us that might help us duplicate the issue? What do you mean by it working “in this same configuration before” ? What does that mean? That suddenly it just stopped working? Or did you upgrade fog or make a change and then it stopped working? If you performed an upgrade and it then stopped, what version did you upgrade from? We just need more details to help us try to figure this out.

@Wayne-Workman
When I said in the same configuration before, I meant that until now I had never slowed down with my FOG server.
I think it’s since RC19 or RC20 that I meet my problems.
What is strange is that when I restore a computer room with 30 pc for example, I do not have an error message at the beginning, then gradually I have more and more message until the Link between the waiting machines and the server does not do any more at all (the client machine does not know on what queue it is and does not find the storage node).
I will try to switch to RC26 during the day
I am sorry for my English, I hope to have made me understand

Wayne Workman · Nov 30, 2016, 1:59 PM

@Lombard Why not multicast?

Also, what is the link speed between this lab and the FOG server? I am assuming it’s either 100Mbps or 1Gbps.

What speed is the FOG Server operating at? You can see by installing ethtool and then checking the link speeds.
apt-get install ethtool -y
ethtool eth0 for the eth0 interface.
It could be possible that the server has a degraded link (from 1Gbps down to 100Mbps).

It could also be a failing HDD in the FOG Server that is slowing things down.
