Apache ProxyPass：连接超时

我已将 Apache 配置为将一些流量代理到内部 IP（127.0.0.1:8048）。访问内部 IP 时，一切正常。但访问代理时，我收到：

无法连接到 matrix.DOMAIN 端口 8448：连接超时

我在 ufw 中打开了端口 8448，所以我有点不知道这里出了什么问题。我希望得到有关如何调查此问题的建议。我的 apache 配置如下：

# Server-Server (federation) API
# Use this apache reverse proxy template to enable matrix server-to-server federation traffic
# Be sure that network traffic on port 8448 is possible
#
# You can check your federation config at https://federationtester.matrix.org/
# Enter there your base DOMAIN address, NOT your matrix.DOMAIN address, ex. https://DOMAIN
#
# In this example we use all services on the same machine (127.0.0.1) but you can do this with different machines.
# If you do so be sure to reach the destinated IPADRESS and the correspondending port. Check this with netstat, nmap or your favourite tool.
