we are plagued with the problem of networking and rancher desktop not being able either to download kes images at start or not being able to pull images. We have an enterprise proxy and this could be the problem and also VPN and this could also be another source of problem (than I red in this channel that there is also the MTU topic) also the DNS could be another factor. Can someone helm us and all the rancher desktop community run a set of tests to identify the problem and hopefully find a solution?

probably just the proxy as there is minimal clean proxy support in the product today. Lots of “it depends” and timing for the most part especially on Windows. Mac is a bit better because the full VM is a bit easier to manage. VPN can drive issues w MTU. DNS should be pretty solid with the hostresolver so without any specific errors its hard to know your issue. Have you jumped into the shell (

rdctl shell

) to see what is working and what isn’t?

either a DNS problem or a firewall

but there is no chances to have network working

also tryed to change the nameserver to 8.8.8.8 with no success

the screenshot is from the colleacue that has the problem and is at home with wifi+vpn and no docker run or docker pull

looks like it found a DNS name for docker.io and it looks like proxy is your issue.

we also tryed to deactivate firewall defender just in case with no success

no since we also tryed to curl by IP

did you try to curl something on your intranet?

powerful-elephant-25838

10/06/2022, 2:19 PM

in linux there is no proxy info and also in the windows env no proxy

wide-mechanic-33041

10/06/2022, 2:20 PM

so you don’t have a proxy on the other side of the VPN?

you have a direct route to the internet from your corp network to the internet basically

I still have to undestand out network since it seems to be a mess 🤔 but when we have to use VPN we do not need proxy

we tryed both by IP and also on an interna IP with no avail

how can I chack if the windows firewall is in the way?

wide-mechanic-33041

10/06/2022, 2:25 PM

look at the firewall logs

powerful-elephant-25838

10/06/2022, 2:25 PM

we disabled but I'm not sure since this behaviour is too strange and all seems to point to it

can you point me to where logs are placed?

could it also be the antivirus?

we have mcafee trillix

hard for me to know your configuration of your security tools. https://learn.microsoft.com/en-us/windows/security/threat-protection/windows-firewall/configure-the-windows-firewall-log

and if your VPN has broken routing for the WSL2 instance it could be the cause. if you cant ping an intranet resource from your the rancher shell, but can from your windows CMD than i would think your vpn has broken the WSL2 routing

powerful-elephant-25838

10/06/2022, 2:36 PM

could be BUT how can we fix it?

wide-mechanic-33041

10/06/2022, 2:36 PM

work with your vpn supplier

some say use of hyper-v virtual switching is not supported on vpn clients

ummm but only with those 2 PC?

wide-mechanic-33041

10/06/2022, 2:37 PM

no clue on your counts or configs just trying to point at places to look

powerful-elephant-25838

10/06/2022, 2:37 PM

because the strange thing is that these 2 colleagues are the only 2 unlucky ones that have this problem

all the others do not have this problem (and all PC should be fairly similar)

we'll try to build up a matrix of all versions and pieces

will send you all updates

thats good news as you have a known good. so you just need to diff the machines. see what works and move step by step forward. start at basic network checks from the distro to more complicated interactions

got a couple of news, installing on the same PC so under same conditions a ubuntu distribution it manages to exit using curl (things that it did not manage to do before

so the problem could be in the resolv.conf and wsl.conf of the rancher desktop distro?

wide-mechanic-33041

10/06/2022, 6:31 PM

well resolv.conf should just point to the host resolver process which forwards queries to whatever dns is configured on the host

powerful-elephant-25838

10/07/2022, 9:07 AM

but is the host_resolver process something that comes with rancher desktop or is from windows? since it seems that ubuntu is getting the info properly and rancher desktop no

in the ubuntu we have this

and this works

now we tryed to do a factory reset and we get this

Copy code

Error: connect ECONNREFUSED 192.168.1.2:6443

so lots of things going on here. did you test networking, ping an ip, ping a name, curl an internal site, curl an external site?

powerful-elephant-25838

10/10/2022, 9:49 AM

yes we did: the host is working correctly as espected and also the Ubuntu distribution installed on WSL as a second distribution to test it ... so wsl and windows are working correctly is the rancher desktop distro or something else that is not connecting to the network at all; now we will try to uninstall it and reinstall it to see what happens, do you have any hint of what could have gone wrong?

wide-mechanic-33041

nope not enough data to make a call on what might be the issue

here is some results:

1. Download wsl-vpnkit.tar.gz and copy in C:\Users\<username> 2. Open PowerShell in C:\Users\<username> and execute wsl.exe --import wsl-vpnkit $env:USERPROFILE\wsl-vpnkit wsl-vpnkit.tar.gz wsl.exe -d wsl-vpnkit wsl.exe -d wsl-vpnkit service wsl-vpnkit start 3. Open WSL rancher-desktop wsl -d rancher-desktop Go to root /mnt/d/tmp/extractor # cd /root edit ~ # vi .profile add and save wsl.exe -d wsl-vpnkit service wsl-vpnkit status >/dev/null || \ wsl.exe -d wsl-vpnkit service wsl-vpnkit start 4. restart Rancher Desktop 5. Open PowerShell check WSL wsl-vpnkit e rancher-desktop are running with this:

wsl -l -v

NAME STATE VERSION wsl-vpnkit Running 2 rancher-desktop-data Stopped 2 rancher-desktop Running 2 Open WSL rancher-desktop wsl -d rancher-desktop check ping # ping 8.8.8.8 PING 8.8.8.8 (8.8.8.8): 56 data bytes 64 bytes from 8.8.8.8: seq=0 ttl=64 time=2.328 ms

please see if this helps you understanding if there is something that has to be added to RD. This solved the problem for us
