'Are there new security measures in Centos 9 for retrieving remote files?

Summary: Centos :

Attempting to download a specific file sometimes works, other times hangs with a "Resource Temporarily Unavailable"

Details:

The file is downloaded as a part of Playwright (https://playwright.dev)

file: https://github.com/sass/node-sass/releases/download/v4.14.1/linux-x64-72_binding.node

Our IT department says it's triggering their monitoring, but they are not actively blocking it.

The trigger is listed here: (14978)

https://knowledgebase.paloaltonetworks.com/KCSArticleDetail?id=kA14u000000HBwCCAW&lang=en_US%E2%80%A9

On the machine, I have disabled:

  • selinux
  • sophos av
  • firewall

If I run the download repeatedly on centos/rh 7 machines, it never hangs. It's only on centos9 does it start to hang after 1 or 2 downloads. The download hangs/fails on wget and npm.

All machines are exiting our labs from the same IP address, and it's not being requested multiple times per second.

I'm at a loss what to keep looking for. If there's a new security measure, I can't find it.

Any thoughts or additional areas to check are welcomed.

thank you !
