Hey there @filcole, mind taking a look at this issue as its been labeled with an integration (nissan_leaf) you are listed as a codeowner for? Thanks! _{^{(message by CodeOwnersMention)}}

As noted here -- https://community.home-assistant.io/t/nissan-leaf-component-s-platform/38663/506 -- it appears that the Nissan servers are erroring based on a User-Agent field sent by the pycarwings2 library. I applied the fix mentioned in that comment, replacing the User-Agent field with an empty string, and it started working again for me.

Looks like the dodgy User-Agent was added here: https://github.com/filcole/pycarwings2/commit/4005247aa51127f8b999ebdbeb15c48bceb8390e and is new in pycarwings2 2.10.

I have updated to core-2021.8.8 which I thought consumed the new pycarwings2 library, but the error persists.

Still an issue in 2021.9

as described in https://github.com/filcole/pycarwings2/issues/26#issuecomment-919905673 , pycarwings 2.11 is now in HA 2021.9.6 and should be working, but unfortunately I think Nissan have made another breaking API change. details in that comment.
