I'm running uvicorn in combination with gunicorn like this:

gunicorn -k uvicorn.workers.UvicornWorker --forwarded-allow-ips "*" ....

This worked well with the 0.30.6, however it's broken with the 0.31.0 of uvicorn. The issue got introduced with the PR [1]. The problem is, that the check for the wildcard changed. In the old version there was a check like "*" in trusted_hosts. The new code now checks for trusted_hosts == "*" which causes the problem.
