troubleshooting possible network problem - adrian - 05-08-2017 15:08
In another thread it was suggested that I might have a network problem.
I'm using a NetGear AC1450 router running
Code:
Firmware Version DD-WRT v3.0-r27506 (07/09/15) std
Kernel VersionLinux 3.10.83 #4384 SMP Wed Jul 8 05:59:05 CEST 2015 armv7lI looked around for an IGMP snooping option as suggested on the support page, but I haven't found such an option. (There is "optimize multicast traffic". Is that related? That option is currently off.)
I'm not sure what other information is relevant to troubleshooting. As I noted in the other message, I've only noticed problems connecting to MinimServer with Hi-Fi Cast. (I suppose it could be that other apps are having intermittent problems but are better at recovery.) I have had problems connecting to Chromecast from BubbleUPNP where it basically fails all the time with NETWORK_ERROR.

In your previous post about this on the other thread, you said:
Another observation is that after my NAS did an OS update, hi-fi cast lost contact with MinimServer and was not able to re-establish the connection until I rebooted the tablet.
What is happening now when you boot the tablet? Does Hi-Fi Cast see MinimServer? If so, how long does this continue before Hi-Fi Cast can't see MinimServer any more?

Hi-Fi Cast is working right now. I'll wait to see when it fails next. I've so far had two failures since I started using it on July 30. If that's a pattern it's about 2 days.

I didn't answer the question "what happens when I boot the tablet?"
The answer is that before I booted the tablet, in both cases, Hi-Fi Cast was showing that Minimserver was "offline" and it displayed an "X" on the list of servers. Nothing I did would change this, even though other devices were talking to Minimserver.
After booting the tablet Hi-Fi Cast was again able to contact Minimserver without any obvious problems.

About an hour ago I tried to use Hi-Fi Cast and it had again lost connection with Minimserver. I rebooted the tablet and the connection was restored.
RE: troubleshooting possible network problem - simoncn - 07-08-2017 09:38
Does it lose contact after the tablet sleeps and resumes (perhaps for more than 30 minutes)?

I normally have the device set to stay on all the time. To answer this question I changed the settings so it would shut of the display and let it stay off for about an hour. When I resumed Hi-Fi Cast was still able to access Minimserver.

This doesn't have the normal symptoms of a network multicast problem. Hi-Fi Cast is showing one of my MinimServer instances as offline, with a second copy of the same instance shown as online. Touching the Refresh button in the Hi-Fi Cast server list doesn't correct this problem. There might be some issue with how Hi-Fi Cast implements the UPnP discovery protocol.
RE: troubleshooting possible network problem - adrian - 08-08-2017 12:24
To me it seemed like if I had a network problem it should have manifested with other apps and under more circumstances. I find the same thing, that the "Refresh" button on the Hi-Fi Cast server list doesn't have any effect. I think I mentioned before if a sporadic network problem is present but other apps recover better that could explain it, I guess.
There is also still the question of why BubbleUPNP gets NETWORK_ERROR when trying to use chromecast. Last night I was able to chromecast from BubbleUPNP (I only tried for a few seconds) and this morning it was no longer working.

You could contact the BubbleUPnP developer to ask if there is a log that might provide more details on this error. If this can be fixed, it might fix the other problem as well.
