Next PVR web server (access listings/recordings from remote PCs) doesn't always start

[martinu]

I'm running NextPVR 3.9.2 on a Windows 7 PC. On the Settings | Clients page, I've enabled Web Server, using the default port 8866. The PC is hard-coded (by address reservation on my router) so it is always given the same IP address.

Other PCs and my mobile phone can browse to 192.168.1.8:8866 and see the listings and the recordings - usually...

But after a reboot of the NextPVR PC (eg after a power cut) the web server does not always seem to work. I can see this by running a TCP port-finder such as NMAP: the PC not listening on port 8866, which it normally does. Even if I run a browser on the NextPVR PC (as opposed to another one), there's no response.

Everything else works: the server can still access the recording device, it can still get listings updates. The recording service is running. The NextPVR console application is running. Other TCP services such as SMB/NetBios (for \\server\share access to folders) work fine.


The only remedy I've found is to kill the Ntray process and restart the NPVR recording service (which restarts Ntray), in the hope that eventually the web server will start listening on port 8866 - usually three or four kill/restart cycles will eventually kick it into action.

Does anyone have any suggestions for what other diagnostics I could run.

NextPVR Settings --> About has a button that will zip the logs. Attach the logs to a post stating the time that the web server was not working so that we know where to look in the logs. Thanks.

Edit ... Bugger ... Found the other post where you have done exactly this.

You can close this thread: I've seen an earlier thread https://forums.nextpvr.com/showthread.ph...post514511 (although I have Win 7) and posted my logs there.

You should not have posted on that thread it is unrelated to your problem so keep this open. Some people need to run delay start on the service to get the web server running. I would start with that.

You also seem to be having problems with your scan killing ndigitalhost and might need to work that out with sub.

Ah OK. I wasn't sure whether it was a problem that was affecting more than just Win 10, even though it was initially reported on Win 10.

I've uploaded the evidence to this thread, for completeness and to avoid people having to go to the other thread.

I've changed NPVR Recording Service to "Automatic (Delayed)" in Control Panel | Admin Tools | Services, so it will be interesting to see what happens.

When I've finished recording the Tour de Yorkshire bicycle race (it passes through the area where I live) I'll trying rebooting the PC and see whether everything starts properly.

I'm intrigued by what could be killing NDigitalHost. You refer to "my scan" - is that the EPG scan for programme listing updates. It will be interesting to see whether that killing of NDigitalHost stops a web server that was originally working when I first rebooted. What you mean by "you may need to work that out with sub"?

If you create a c:\temp directory, are you getting a c:\temp\crash.mdmp file created when ndigitalhost.exe has problems?
