Server inaccessible

[crusher11 975]

A few days ago I started getting 521 errors from CloudFlare when attempting to connect remotely. Local was working fine, though.

Emphasis on was, as I am now no longer able to connect via LAN either.

HI there, let's look at an example of your issue:

Thanks.

Hmm. It turns out it wasn't running, so it evidently just shut itself down at some point. I've attached what I assume to be the last log before the shutdown.

This is unhelpful, as everything there assumes the server can be accessed.

It does have this line:

If you're having difficulty using the web interface, logs can found in the Emby Server Data Folder.

I don't see anything obvious here, so I would just start up the server and see if it happens again. Doesn't look like there was a crash. You click restart and it shutdown without coming back up I guess.

Those aren't anonymised, are they?

I didn't restart it. I didn't touch it.

Why was this moved to the testing area?

Well it's in the log. An http request came in from the web app to restart.

Oh, it's probably the wrong log. There were some plugin updates requiring a restart when I got it back up.

OK I don't see anything obvious there. If the process shutdown then I would check windows event viewer.

When troubleshooting something like this it's a good idea to remove unknown variables that could be coming from plugins:

	Bulky 1.0.20.0
	Chapter API 1.3.0.8
	Classification Mapper 1.0.0.4
	Com Skipper 1.2.3.0
	Iconic Image Enhancer 2.4.0.0
	Intro Skip 1.0.0.3
	Intros Backup 1.0.0.6
	Playback Reporting 2.1.0.5
	Pushbullet Notifications 3.1.7.0
	Smart Playlist 2.4.0.1
	Statistics 3.2.0.0
	Strm Extract 1.0.0.0
	Vantage Point 2.1.0.5
	VirtualTV 2.0.2.0

Again, that advice is completely unhelpful because it was a random shutdown. I cannot remove plugins and test if that changes anything because I have no way of knowing what to do to reproduced the circumstances that caused the crash in the first place.

It's also not a Windows install, so Windows event viewer is unlikely to be helpful, although it's worth noting that I did get a BSOD on my Windows PC around the same time as the Emby crash.

I'm still unable to connect remotely, however.

Hi there, what exactly happens when you try?

Only way to test if it is a third party app or not is remove them as this would appear to be a specific issue to your setup.

But for sure per errors in your log Smart Playlists has issues.

Unless debug logging shows more there is really nothing in the log if it stopped/shutdown at 0418 as the only thing going on was a library scan getting a lot from TMDB.

Hi there, what exactly happens when you try?

I was getting a 521 error from CloudFlare. Having switched CloudFlare from proxied to DNS only, I'm now getting an "unable to connect" error from my browser.

[Luke 40065]

What is the full and exact message that you get?

[crusher11 975]

Unable to connect

An error occurred during a connection to [my domain]

    The site could be temporarily unavailable or too busy. Try again in a few moments.
    If you are unable to load any pages, check your computer’s network connection.
    If your computer or network is protected by a firewall or proxy, make sure that Waterfox is permitted to access the web.

[Luke 40065]

Is the server process running?

[crusher11 975]

It's accessible via LAN, yeah. The WAN access issue has been ongoing for several days and is unrelated to the crash from last night.

[Luke 40065]

Hi, did you figure this out?

[crusher11 975]

Yes, it was an NGINX config issue so it ended up being discussed in that thread.
