suddenly no internet access on my server, please advise

What are the network settings and are all drivers installed?

If the addresses are obtained via DHCP, it is best to set them up statically and test again.

Hello

i have a RS 4000 G11 with windows on it, i tested the server for like 20 minutes, then suddenly no internet acesss

please help

Same problem for me (RS 2000 G11)

Does it work with the static setup?

If not, please contact netcup. If it is urgent, there is the possibility of emergency support.

My root server was working for about 3 months without any problem. But today internet connection problem occured. I can't access server via ssh, just only with SCP VNC Console. When i try to ping any domain i get error, i can't do speedtest or git pull operations.

and one more question, do you know why my windows 10 system can only recognize 4 cores since my server has 12 cores?

This can be set in the SCP.

- Settings - CPU structure

It is possible that netcup is having problems with the distribution via DHCP.

This could be the reason if your network is set up in this way.

If your network is set up statically and it does not work, further research is required.

windows or linux?? my linux server has no problem

linux server. i think there is a problem with dns resolutions. i have restarted the server about 10 times, the problem still persists. maybe it is a partial problem for some servers. it started about 3 hours ago.

Which DNS servers are used? You do not have to explicitly use those from netcup.

If this is the case, simply use another DNS server of your choice.

The support team hasn't gotten back to me yet. They'll probably get back to me tomorrow. I'm looking to see if I can come up with a solution myself. I wonder if changing the network driver will help?

A change of driver could help solve the problem. However, you have not yet explained how your network is set up.

I can not modify /etc/resolv.conf file.

I didnt make any configuration about network. they set up a debian server and i started to use it. i have no idea about network set up.
