I was running LNM 2.8.12 for months and everything was fine. I decided to check out the new beta, so I updated to 3.0.3. After the update, the web view looks like the screenshot below. (latest FF on Win11).

Checking the browser console, it's full of 404s on the images, css, js. But those files ARE in the webroot folder on disk.

I checked my firewall and nothing seems to be blocked. I've disabled all my browser plugins, and tried 3 different browsers (FF, Chrome, Edge). Nothing works.

I tried downgrading to 3.0.2. Same issue.

I tried "legacy ui" and without. No fix.

When I downgrade to 2.8.12, everything works fine again.

Any help appreciated!

thanks,

Robert A.

Networking stuff has changed in 3.0 and there are probably problems in LNM or it shows problems in the user's network configuration.

What you see are most likely incomplete remains of the web page in the browser cache. 127.0.0.1 is the same as "localhost" and should always work. You can also try "http://localhost:8965".

Possible issues which may cause this:

1. The firewall blocks access some reason. Try one of the other addresses in options on page "Webserver". Best is "http://yourcomputername:8965"
2. The port 8965 is already blocked by another service. Try another in LNM options.
3. You've changed the base directory to an invalid folder in options on page "Webserver". Clear the input field to use the default.
4. Some browsers enforce https which is not enabled per default in LNM. A user cannot see this in the browser's address bar since http/https is hidden.

If all else fails send me an issue report.

Hey Alex!

Thank you very much for your quick reply and suggestions.
You're right: the issue is definitely with my Win11 PC. I've installed LNM on one of my Linux computers and the web page generated from there works perfectly. I can open that page fine on the local machine as well as on other machines on my network (including on my PC, so my browsers are not the culprit).

But the page generated by LNM running on my Win11 machine can't be opened properly on the local PC nor on my network devices. Only the HTML loads, like in the screenshot I posted last week. But no ressources load. So there's something preventing the LNM server from running properly...

I've tried some stuff, but no success:
- I completely turned off the firewall on my Win machine.
- I made sure the LNM port is free, and I also tried another port just in case.
- I made sure LNM is using the default web server directory. I also entered the directory by hand just to test.
- Copied the "web" subdirectory from the Linux install over to the Windows machine, just in case something got messed up on installation.
- Open up permissions on the LNM folder and its subfolders (including "web").
- Did another complete uninstall, including removing all files, data, settings, etc.

Nothing worked. If you have any more suggestions of other things I could try, I would appreciate it.

in the meantime, I'm running the older version and it works well.

Thanks,
Robert.

Hi Robert,

sorry, stupid me.😑 
There is a fix in the LNM web server which might help with your issue too.

You can try a pre-3.0.4 here: https://k00.fr/q8vl9pyl

Keep in mind that this version will not remind you if the final 3.0.4 is released. Better check the Avsim forum here or the feed on my site.
I have to do more more updates to this.

Alex

Hey Alex,

I confirm that the issue is fixed!! 😁 As soon as I installed 3.0.4, the web page started working properly.
Many thanks for the quick fix and for all the work you're doing with this amazing software. It's really impressive.

And you never have to say "sorry". I do dev work too, I know how sneaky some bugs can be.

All the best!

Robert.

I'm having this problem on 3.05     The computer running LNM has an ethernet connection to the router as well as a wifi connection.  My phone and tablet are both on the same wifi network but can't connect.   A ping tools app on my phone does reveal the PC name and it's IP address, but chrome on both devices won't load it.

You have a different problem than the OP if you even cannot connect.
Often it is a Firewall issue where the connection is blocked. Having both a Wifi and Ethernet connection is no issue. LNM will listen on both interfaces.

You can try a Ping app to check network connectivity to the flying computer. But even then, the port to LNM might be blocked by an overzealous firewall.

Well I did the bad thing of changing two items and then wondering which fixed it.  Turned off wifi on the gaming PC so it had only the ethernet connection AND set up a reserved IP on the router for that ethernet adapter.   Now on my phone, using the IP and port, LNM shows up.    Using PCname: port    it doesn't, but I can live with that.

Name resolution in local networks is a bit touchy. I also have some devices here which I cannot find by name or where it takes forever to resolve. In some I have to add the domain like "computer.fritz.box" "computer.home" to find them. IP-address is a good fallback then.

is there a way to increase the rendering resolution of the map in the web server external browser?. I mean, it looks great on the little nav app but trying to open it in my android tablet and it is ok, but nothing close to the native pc. All is in local network.

No idea what's wrong there without a screenshot. Too small icons? Wrong layout?

You can change a setting in some browsers to show the page in desktop layout. Maybe this helps.

thank you for the quick reply, I will post a screenshot soon. What I mean is that it is low resolution compared to native desktop app map. Also, now that we are here...is there a way to add more info next to the moving plane in the map additional to GS and Altitude?

Thank you!

Yes. See here in options dialog:
