Hello Guys, how are you?

Im receiving logs of error from my Swift (openstack 3.12.1) installed with packstack (centos-release-openstack-pike). My swift configuration is default yet. I'm trying to make backup on my swift in a internal L3 network through a backup tools (Spectrum Protect). After about 2 minutes, I receive logs with error connection:

Are you sure 10.18.1.30:5000/v2.0 is correct? Keystone version 2 was obsoleted years ago.

If yes, what happens when you connect manually, e.g.

curl http://10.18.1.30:5000/v2.0

The same or a similar problem has been raised as a bug: https://bugs.launchpad.net/python-swi.... This is a bug in the swift client; not sure if it applies to your situation.

Can you configure Spectrum to open fewer connections?

I suggest you get help from the distribution list.

Unfortunately I do not think so. I will create a virtual machine in lab for tests ..
