NF does not perform proxy authentification and cannot access github

Bug report

Doesn't authenticate at the proxy server, no internet access

Expected behavior and actual behavior

We have a computing cluster with internet access provided via proxy. Most programs take the credentials from the environmental variables and work just fine. Nextflow doesn't try to authenticate.

Steps to reproduce the problem

install nextflow, install graalvm, run
)->nextflow run nf-core/demo -profile maestro --input samplesheet.csv

Program output

N E X T F L O W ~ version 24.10.3

Pulling nf-core/demo ...
WARN: Cannot read project manifest -- Cause: Unable to tunnel through proxy. Proxy returns "HTTP/1.1 407 Proxy Authentication Required"
Cannot find nf-core/demo -- Make sure exists a GitHub repository at this address https://github.com/nf-core/demo

Environment

• Nextflow version: 24.10.3
• Java version: graalvm 22.3.1
• Operating system: Linux RHEL 8.6
• Bash version: 4.4.20

http_proxy=http://user:mysecretkeyhere@squid:3128

Additional context

Proxy is required for security and audit.

Can you share your Nextflow log? You should see these two lines if http_proxy is set:

Setting http proxy: ProxyConfig[...]
Setting http proxy authenticator

[kpetrov]

nextflow.log

thanks for a quick reply, here is the log with some debug info

[bentsherman]

From the first lines of that log it looks like it is setting the proxy credentials for http and https. So I'm not sure why it would fail

[kpetrov]

can I provide any further information? if so, which?
