Hi,
We've got a collection of Ubuntu 18.04 boxes out in the field. They connect to an AWS OpenVPN VPN and use a Squid 3.5 AWS hosted Proxy. They work fine.
We have tried upgrading one to 20.04. Same setup. From the command line curl or wget can happily download an Ubuntu package from the Ubuntu Mirror site we use. But "apt update" gets lots of "IGN:" timeouts and errors.
The package we test curl with is
https://mirror.aarnet.edu.au/ubuntu/pool/main/c/curl/curl_7.68.0-1ubuntu2.5_amd64.debThe Squid log shows a line the doesn't occur for the successful 18.04 "apt updates":

While running, the line
0% [Connecting to HTTP proxy (http://vpn-proxy-d68aca8a8f7f81d6.elb.ap-southeast-2.amazonaws.com:3128)]
appears often and hang for a while.
I've tried upping the squid logging and allowing all, but they didn't offer any additional information about the issue.
Any advice would be greatly appreciated.
