Experiencing '403::Unknown client' error

[sschimper-splunk]

Hi,

I am using the aiosfstream package to connect with Salesforce's Streaming API, and I am receiving the following error: server error response for Channel (/meta/connect): '403::Unknown client'. We have reasons to believe that this happens because load balancers on Salesforce's side switch the target servers to which an connection is established (this is e.g. discussed here: https://help.salesforce.com/s/articleView?id=001119042&type=1).
We further believe that when this happens, pre-existing authentication is disregarded.

Is this something you could please take a look at? I'd greatly appreciate it, and want to offer any assistance if I can.

Thank you!

Furthermore, the issue happens when the aiocometd dependency tries to establish a connection with the _send_payload_with_auth in the base.py file).

For broader context, we are using the Splunk Add-on for Salesforce Streaming API
to onboard the query results to Splunk. This add-on uses the aiosfstream in the backend.
