        @jokurinopoloski are your USB NICs running on VLANs? If so, you could check /var/log/kern.log for xenbr2: dropped over-mtu packet: 1502 > 1500 [...] messages. Maybe not related, but I had a problem with connecting to a NFS SR. While ping and SSH worked, connecting XO from source to the NFS SR failed. After changing the USB NICs MTU from 1500 to 1502, it did work.

          Okay I un-installed the Management Agent on my windows VM and now i'm able to go on the internet without any problems! the downside is that the vm now uses the default "Realtek RTL8139C+ Fast Ethernet NIC" adapter which gives me 3-6 MB/s file transfer speeds..

          a fresh ubuntu install works out of the box, I can connect to the internet. I made a test folder on the ubuntu VM and copied an ISO file to it (from my main windows pc) which gave me speeds of up to 239 MB/s.

          Could the Management agent really be the issue here? and why do I need it for gbit speeds.

            On Windows, it's not just the management agent, but PV drivers for your Windows. Without PV drivers, you are using emulation and it's… slow.

            What drivers did you used previously?

              @olivierlambert I have been using the PV host adapter (PV drivers). It comes with the ManagementAgentx64.exe that can be found on the official Xcp-NG.ISO.

              After un-installing and using emulation, it works fine, but around 30Mbit. When re-installing the PV drivers I get SSL errors again.

              I'm trying to think what the problem could be, the PV drivers? the PV drivers who can't get along with the 2.5Gbe USB attached to the Xcp-NG server?

              Isn't Xcp-NG just passing though it's connection to the VM?

              Those are the questions I'm asking myself right now and I'll try digging into it on google a bit more.

              Really strange that Ubuntu and in my case, Freenas works without problems.

                @gskger Changing the MTU didn't help unfortunately šŸ˜ž I'm starting to think there is something else going win combination with the PV adapter drivers.

                  I don't remember we bundle anything for Windows, @stormi ?

                    @olivierlambert up to XCP-ng 8.1 we had the installer for management agent in a client_install directory on the ISO as in Citrix Hypervisor installation ISOs.

                      HOLY MOLY! I think I fixed it by disabling TCP offloading according to this article:

                      https://docs.aws.amazon.com/AWSEC2/latest/WindowsGuide/pvdrivers-troubleshooting.html#citrix-tcp-offloading

                      Internet works without ssl/tls errors! I'm going to check right away if I can get the 2.5Gbit speeds!

                      EDIT: As of now I get 1.70 Gbits/sec with an Iperf3 test, this is amazing! Not getting the full speed is probably because of VM overhead or the cat5E cables who aren't that shiny anymore.

                      I want to thank you all for taking the time to help! It must be a pain sometimes! Especially people who revive old threads. BUT I can finally follow my VirtualMachine dreams I had planned for a long time. You guys are amazing, I've been using Xcp-NG for a year and there will be many more years to come!

                      Merry Christmas! And I hope this thread will help a lot more xcp-ng fans!

                        Nice šŸ™‚ I think we might document this in our doc, maybe in the troubleshooting section!

                          Agreed. @jokurinopoloski, could you try to contribute something to the https://xcp-ng.org/docs/troubleshooting.html page? ("Help us to improve this page!" link at the bottom)
