Steps to reproduce

• I do not have a good idea on how to reproduce this bug, but keeps crashing my live instance.

Expected result

Hikari shard should be stable

### Further info

I'm hosting it via railway.
I tried adding a domain (https), but didn't fix the error.

[null-domain]

This bug has been mentioned a few times in the hikari server - it's an issue with running hikari on Python 3.11.
This issue will be fixed as of version 2.0.0.dev119.

For now, please do either one of the following:

• Install fix from a temporary 2.0.0.dev119 branch:

pip install git+https://github.com/davfsa/hikari@task/dont-force-close

• Add the following lines to your bot constructor:

+from hikari.impl import config

bot = hikari.GatewayBot(
    "TOKEN",
+    http_settings=config.HTTPSettings(enable_cleanup_closed=False)
)

IIRC, the second option will become the default in dev119 (and is the change that installing from the above branch makes).

Thanks for the report! This is actually an issue with changes in CPython 3.11, but regardless, this will be fixed by #1585
