ARC Diaries: A Bittersweet tale of love & loss

Somehow, ARC launched successfully when I was at Martin Webster’s house, recently. Presumably it knew it was in the presence of a moderator & daren’t do otherwise.

That day I was able to to the drive home & had several hours of uninterrupted music. Bliss!

Since then, nada. I just cannot get this fickle thing to work.

Right now, I’m sitting in my own living room, 12" away from the server & nothing. I’ve re-started everything.

Also, I’m now getting a dropdown thing that I cannot dismiss.

This is not the Christmas present I was expecting.

Yeah, it happens often with the my large music library (stored on a NAS) when playing at home through Roon on my Sonic Transporter or my iphone ARC app, Roon server will crash. Roon ARC doesn’t show a message that Roon Server is rebooting but that is what typically happens in my case. I wish Roon memory build-up or whatever happens causing Roon Server to crash/reboot will get fixed in the future. It takes less than 5 minutes for it to restart on it’s own, but it’s never a good time when it happens…

Why do you use ARC in your house when Roon Remote is available to you?

I still find that ARC has problems context switching between my LAN and cellular connections, so I just quit the app if I have to perform that context switch, and everything works perfectly.

:rofl: I don’t use ARC in my house, but since I can never get the sodding thing to work when I’m not in my house, I decided to take my phone off wi-fi & see if I could get it to connect whilst I was sitting by my computer & able to troubleshoot the connection issues before heading out.

Sadly, I wasn’t able to get it working.

Hi, @Snowdog, we reviewed your diagnostic reports. It looks like your RoonServer was having troubles pinging our authentication services. What’s is interesting the problems persisted even you rebooted your RoonServer. That’s why you saw the Core unreacheable message, unfortunately. Could you, please, tell me what’s the behaviour of Roon ARC now?

Thanks!

Well, just for a laugh, I tried to launch it earlier & I got this message:

So I was due to come on here & ask how best to troubleshoot that.

Now I’m home & on the same wi-fi network as the server, I get lots of interesting messages, but at the end of the day, it’s still just spinning up & searching for Roon server. Or it identifies the correct server but shows me a screen that is completely frozen.

Honestly I can’t help but wonder if something is monumentally screwed at this end.

What settings can I look at? Port numbers? Some other thing that’s more or less meaningless to me but means something to you?

I have posted elsewhere about some of the things that happen on this MacBook, but right now Dropbox is inactive & the activity monitor is pretty much flat-lining so I don’t think it’s those, this time around.

I use ARC at home & find it does switch between cell & Wifi ok, I use it if I am in & out the house beyond the reach of wifi, back & forth in the yard etc. This is with Android 14 on a Pixel phone.

I’m sure mine has switched before now, back in those heady days when it worked & I’m sure it will again, once we can figure out what part of my system thinks it’s being told a bible story & shuts down as a result.

Okay, well I’ve set up just the one computer now that the house is quiet again, in the hope of ruling out some of the bits of gear that are usually in the networking loop & currently aren’t.

Most of the things my computer does… It’s still doing which, on the one hand, is slightly comforting as I can continue using the network once I’m properly set up again. Of course, on the other hand, it means I still haven’t identified the problem.

The current status is that when I launch ARC, it asks if it can use “roonlabs.com” to sign in. (I don’t know what I have to do to make this the route without it having to ask every time, but anyway…) I click continue & it takes me to a white “welcome back” page & I click on my name.

It briefly shows some text that’s too quick to read & settles on the following, which is a completely locked up page that will do nothing:

When I was at Martin Webster’s place, it loaded up my library & I had uninterrupted music all the way home from there. You (@Ivan) mentioned that there was an issue to do with pinging the server.

Could this be setting on my iPhone or my home network that didn’t exist on Martin’s network?

It sounds as though you have an ad-blocker active on your phone (or a website blacklist active in your network?) that is disturbing the sign-in process?

BTW, I removed your email address from the screenshot - I know it’s an image, but not a good idea to post private addresses in a public forum…

Sorry, that’s not the first time I’ve done that. I appreciate your diligence. :slight_smile:

Okay, yes, I have ad blockers everywhere. What should I whitelist?

TBH, I’m not sure of the complete list, but looking in my Pi-Hole data, I see:

api.roonlabs.net
discovery.roonlabs.net
pool.ntp.org

Well, I’ve added the above items to the allowlist of AdBlockPlus but it’s still locking up at the screen shown above. Are there any settings in my iPhone that I might need to change?

@Snowdog, am I getting it right that the following points are correct:

  • You cannot properly use Roon ARC app while your phone is on Cellular (I assumed this based on screenshots you posted above)
  • You are having issues while you are on your home wi-fi network (based on Right now, I’m sitting in my own living room, 12" away from the server & nothing. I’ve re-started everything.)
  • You can properly connect to your RoonServer while being on a different Wi-Fi network at Martin Webster’s place

Thanks!


Ivan

Yes, that’s correct.

Interesting. It confirms that there is something strange in the way how your phone communicates with our servers on Cellular and your home network. In the diagnostics report, I see that you had an auth failure which happened at 1:30am your local time. It looks as if something triggered this while the app running in the background but this fact on its own does not provide a lot of info :frowning:

As for the AdBlockPlus, I am not sure if it can iterrupt the connection since you could use the appat Martin Webster’s place but will it be possible for you to disable it completely and see how things go?

Thanks!


Ivan

Happy New Year!

I disabled the ad blocker & sadly it made no difference.

On the basis that it happens both when I’m on my home network & when I’m not, that would indicate it’s the phone & not my home network.

I’m going to scour my phone settings & see if there’s anything I can tweak. (It has worked on this phone in the past, so it’s probably something in an iOS update.)

One question. Whenever I try & log in to ARC, I get this:

Is this normal? This seems to me as a setting I ought to be able to change so that it doesn’t have to ask every time & I’m wondering if it’s any kind of clue?

Since Dec 12 and Build 1353 I’ve been unable to sync ARC to my nucleus + on either iPhone 15 or iPad using either home wi-fi or cell as set out here

Would be helpful if you’d check my logs

I remember I had the sign on screen issue in Android & it was after I had re-installed ARC & I had also moved my Roon core to a different server & ARC was looking for the old non-existant core, telling me it doesn’t fully uninstall.
I cleared the cache & settings in the Android app settings & then it worked & I signed in.

Hopefully there is something similar in iOS.

EDIT:
This reply is for Snowdog, sorry for not replying to the message.

Okay, so I have a new thing…

For a moment I thought I might have nailed but, well…

Basically, when I got to the sign in screen…

Instead of signing in as I always have, I decided to try signing out. I then signed back in again & everything started doing what it did at Martin’s place. Which is to say it began syncing.

I was quite optimistic until I saw this:

So, are there any updates? Because I ran a Roon update from the main app the day before yesterday & ARC takes me through the Test Flight app whenever there’s a new version.

What do we think?
