Start by reproducing the proxy failure on Fedora Linux 43 with SteamTools 3.0.0-rc.16 and the no-runtime package. Inspect the Yarp proxy service under the reported content root and compare its startup and shutdown logs while accessing both accelerated and unaccelerated sites. Done means identifying why connections fail and confirming that proxy traffic is no longer stuck at zero.
