Web Server Bleg

Geek Alert for this post.

I’m running a web server app on my computer, which I can address by http://localhost:8080/webapp, where “webapp” is the app.

It works fine, but in theory, I should be able to access it from another machine on the network via http://localhostIP:8080/webapp, where “localhostIP” is the IP address of my machine, but I can’t. It just times out.

I’ve even installed Apache on the machine, and I’ve set up a reverse proxy in the Apache config file per the following:


ProxyRequests On


Order deny,allow
Deny from all
Allow from 192.168

#Set up reverse proxy for Webapp server

ProxyPass /webapp/ http://localhost:8080/webapp/
ProxyPassReverse /webapp/ http://localhost:8080/webapp/
ProxyPreserveHost On

Again, where “webapp” is the actual webserver that I’m trying to access remotely.

When I try to access this from either a remote, or my local machine, by http://localhostIP/webapp, I get the message: “The requested URL /webapp was not found on this server.”

Any Apache gurus who can tell me what the problem might be? I’ve opened up firewall to both http and https.

Problem solved. As noted in comments, it was a combination of allowed ports and SELinux.
