Nuget Push fails sometimes

Integration

Hi

I am having an issue which happens sometimes when pushing a nuget package from Jenkins to Octopus Deploy.
Sometimes the nuget server can’t be resolved.
See logs bellow

I tried a few build one after each other all failing, then this one was successful.
From the logs it first could not resolve the remote name for the octopus server, then I retried and it worked.

Hi,

Thanks for getting in touch. The most likely cause of this is a DNS replication issue. Are you able to provide some details about how the Jenkins server is hosted and the network configuration around it? These type of issues can occur, for example, if you have multiple DNS servers and one of them hasn’t updated with the record for thecodegroup.octopus.app. If you happen to hit that server on your DNS request it’ll fail, if you happen to hit one of the others that has the record it’ll succeed.

Hey, thanks for the reply

The Jenkins box is on a Windows VM on a dedicated box in an OVH France datacentre.
The ethernet IPv4 DNS Server is 213.186.33.99 which is an OVH DNS server
There are no other DNS Servers set.

I tried pinging the Url from the Jenkins server and at first we get no IP then after a while we get an ip (with a timeout which I assume is due to the DNS rejecting pings)

Microsoft Windows [Version 10.0.14393]

C:\Users\Adm1nAccount>ping thecodegroup.octopus.app
Ping request could not find host thecodegroup.octopus.app. Please check the name and try again.

Pinging thecodegroup.octopus.app [52.41.91.212] with 32 bytes of data:
Request timed out.
Request timed out.
Request timed out.
Request timed out.

Ping statistics for 52.41.91.212:
    Packets: Sent = 4, Received = 0, Lost = 4 (100% loss),

C:\Users\Adm1nAccount>

It then works for a period then it runs through the same issue again.
I assume this happens again when the DNS records expire

I don’t think the Octopus cloud servers are configured to respond to ping, so the request time outs aren’t too surprising. Not finding the host though is certainly point towards a DNS issue.

Would you be able to run nslookup thecodegroup.octopus.app and tracert thecodegroup.octopus.app and see if the results look right?

Here are my results.
Should I change to a different DNS server or add a fallover?

We’ve done more testing from our end and can’t see any issues.

One point of interest is that I think you’d normally expect the first hop on the tracert to hit the same IP as the server from the nslookup (cdns.ovh.net(213.186.33.99) in your case). It certainly did that in our testing from a number of locations.

Unfortunately this is about the limit of the what I can assist with from here, I’d recommend contacting support for the datacentre to see if they can help understand what is happening.

Thanks
We switched to another dns server and issue is not happening anymore.
