Hello,
I have followed the documentation to create a proxmox offline mirror on a debian 12 server. It is behind a proxy, and I have create the necessary proxy environment variable as follows
ALL_PROXY=http://11.22.33.44:80

but whenever I try to run proxmox-offline-mirror, i get the following error

Code: 
root@debian:/var/log# proxmox-offline-mirror mirror snapshot create debian-bookworm-security
Fetching Release/Release.gpg files
-> GET 'http://deb.debian.org/debian-security/dists/bookworm-security/Release.gpg'..
Release.gpg fetch failure: http://deb.debian.org/debian-security/dists/bookworm-security/Release.gpg: Proxy failed to connect
Fetching InRelease file
-> GET 'http://deb.debian.org/debian-security/dists/bookworm-security/InRelease'..
InRelease fetch failure: http://deb.debian.org/debian-security/dists/bookworm-security/InRelease: Proxy failed to connect
Error: Neither Release(.gpg) nor InRelease available!

I tested the proxy config with tools like wget, and they work fine.

[edit] I tried to run an strace on the proxmox-offline-mirror command, i can see the following error
Code:

The question is, how does proxmox_offline_mirror connect to the internet ? how is it different from normal apt ?
 
well, you can see the request and error in your strace output:

Code: 
sendto(9, "CONNECT deb.debian.org:80 HTTP/1"..., 122, MSG_NOSIGNAL, NULL, 0) = 122
recvfrom(9, "HTTP/1.1 403 Tunnel or SSL Forbi"..., 256, 0, NULL, NULL) = 256
recvfrom(9, "E></HEAD>\n<BODY BGCOLOR=\"white\" "..., 256, 0, NULL, NULL) = 256
recvfrom(9, " -->\n</BODY>\n                   "..., 256, 0, NULL, NULL) = 256
recvfrom(9, "                                "..., 256, 0, NULL, NULL) = 112
close(9)                                = 0

POM sends a CONNECT request to your proxy, the proxy returns 403..

I'm investigating this with the proxy admin
