[Ticket In] B205 Black screen on ARC launch after SSO test

I did the SSO test and everything looked fine. First, while not home, I did the ARC re-login. Later, back home, I logged into Roon. That seemed to work fine generally and is documented here.

So I thought all good, but then launched ARC to re-sync with the Core and all I am seeing is a black screen (with the Android notification bar at the the top and the gesture thingy at the bottom, but black where ARC should be). I quit and restarted ARC repeatedly but no change.

The lock screen control on the phone still shows, though, with the last album I played in ARC before the test, 2 days ago. Android 12, Fairphone 4.

Edit: Rebooted phone, still the same. I am not uninstalling ARC for now in case you want startup logs or something

BTW it is still B205 because I never got the B207 update through the Play store

I deleted the app and reinstalled via Test flight. This worked for me

I had a couple of false starts with ARC, Roon Remote was fine.

After I had signed in using a Roon Remote on Windows 11, I then tried using ARC (B205). The first time I got the home screen with the sync bar running across the top. Then after a few seconds I got this:

I closed ARC down, and restarted and got this:

Nothing further seemed to be happening, so once again I closed down ARC and on the third attempt I got the ARC Login screen. Logged in with the redirect to the browser and ARC started up properly.

Oops - ARC is telling me it is offline, while the Core is telling me that it is confirmed to be securely accessible by Roon ARC.

And now I have restarted ARC one more time, and now it is connected…

Fourth time lucky.

I got the first screen. Shut down ARC. And then it went through smoothly when I restarted ARC.

I’m not so lucky as our esteemed mods, still black after trying 20 times and also rebooting ROCK

Have you gone down the route of deleting storage and cache?

After a few hours of waiting that was the only thing that worked for me

Thanks for the tip, I saw in the other thread. But no, I am leaving it like this for now in case Roon wants to investigate / get launch logs from me, etc. Getting this investigated and solved is more important than me using ARC for now, I’m at home or at work anyway :slight_smile:

Well I hope they can make use of your information.

But this has happened a few times to me now and each time I have had to follow the same process.

I am too impatient to wait for official follow up

I’m willing to sacrifice myself for the community :wink: I once had some other ARC startup issue in EA (occurring after restoring a backup) and after I sent logs to Roon it was promptly fixed, so it’s not in vain I hope

First start of ARC went to black screen for me and seemed to just hang there.

Restarted the app and after a few glitchey screen flickers got to the login page. It then connected with the “first time starting ARC” screen.

Seems to be working now…

Edit: samsung note8

Happened to me on Android, Pixel 6 Pro.

Launched ARC. Saw my library for about 10 seconds, but then sent back to an all black screen. Waited for around 1-2 minutes and nothing happened with no indication anything was happening. Quit app, and on re-launch it asked me to sign-in again. After that all went smooth.

I’m not as lucky. Google Pixel 7 Pro. No joy even after rebooting the phone and getting back on the same network as Core (was on a mobile data network when I logged back in).



This is a pretty terrible user experience. Glad we caught it in Early Access.

Edit: I’ve tried stopping the app and clearing data and cache. got a little further (more photos above). Still no successful connection. B205 was working fine before the forced logout (apart from the USB DAC issues mentioned elsewhere).

Edit 2: I tried restarting Roon Server (on ROCK). After doing so, I attempted to connect via the desktop app. I had to login. After doing so, it took several minutes before I could see the full UI, however, it did eventually come back up. ARC looks like it is healthy (test passes):

However, was still not able to connect via the ARC app, even after clearing cache and data again:

Clearing the data and trying again resulted in a successful connection. Quite an ordeal.


Also Pixel 7 Pro and also on mobile network when I logged back in.
Hopefully the team can use these data points to help improve this for the masses.

Tried on my Samsung Tablet as well, where ARC had not been running in ages. On first start, I saw the normal ARC screen with my library, then it went black after a few seconds. After quitting and restarting, it showed the ARC logo but didn’t get farther. No change at subsequent relaunches. Uninstall/reinstalled and then all good

Appalling App performance following the SSO forced logout.

Had to restart Roon Remote on iOS many times, had to restart ARC on iOS multiple times, had to restart Roon Core, had to put it down and walk away for about 30 mins, while it all sorted itself out again.
And then had to restart Arc to get it working again.

Please, please do not let the general public go through this restart/reboot process

Amen!

Wish there were some logs we could share. Is the Roon team able to gather RUM from our devices? All I’ve got is screenshots.

I once sent them Android debug logs. They will say so when they need
