if you want to see the web page from another client, you must to open the port 80 in your router (internet router) for your server.
for exemple, my server is on a tinkerbaord and his name is nafabox. In my internet box I've open Nat rules 80 on nafabox!!
The two machines are on the same network (home) thus I assume that I do not have to do NAT or port forwarding. The weather radio being run on a StellarMate machine, I can access the StellaMate Control Panel without problem, so it's not a port 80 issue. Any other clues?
On the weather radio machine, if I put http://localhost in the browser, I get the apache2 webpage, as you mention. On another local machine, http://ipaddress gives me the Stellar Mate Dashboard. I thus assume that Stellar Mate redirects port 80 to another port if accessed from outside. If I can figure out how to disable Dashboard this may solve the issue.
Just a thought: is a StellarMate device really the right place running the weather radio web server? Or do you have your StellarMate running 24x7 - which should be the typical mode for a web server of a meteo station?

How to submit logs
so glad you asked the question, it's not clear from the install docs that I should be adding an additional RPi *just* for the web server to not?
to your earlier discussion with @knro in another thread, I feel like the Observatory control systems should be independent from the Telescope/imaging control system, much like Viking and Voyager do - which implies, ideally, two RPis, one of which could host WeatherRadio, Indiunio/relay control, sensors, etc and the other that manages image acquisition.
sorry - this is a thread hi-jack topic, - if worth talking about we should move to another thread. Speaking of which, I will suggest to the web admin team that we should have a section for DIY/Open-source hardware that's INDI compatible as some of these topics are really not INDI per se but related.
