Comment 1 Dirk Mueller 2022-05-10 11:06:58 UTC

I'm not maintaining envoy-proxy and as far as I can see we're not shipping it anywhere. close?

Comment 2 Carlos López 2022-05-10 11:09:47 UTC

As with the other envoy-proxy bugs, reassigning to the appropriate maintainer.

Comment 3 Ludwig Nussel 2022-08-01 13:07:31 UTC

No idea why this got assigned to me. I have nothing to do with this package.
