+
+### MultiPath TCP
+
+Since `v3.4.5`, the MultiPath TCP support introduced with `v3.4.2` has been removed.
+It appears that enabling MPTCP on some platforms can cause Traefik to stop with the following error logs message:
+
+- `set tcp X.X.X.X:X->X.X.X.X:X: setsockopt: operation not supported`
+
+However, it can be re-enabled by setting the `multipathtcp` variable in the GODEBUG environment variable, see the related [go documentation](https://go.dev/doc/godebug#go-124).
