Forgetting the lifetime license key

[SkyNetWhale 0]

Dear Emby team,

A few weeks ago, I purchased Emby Premiere. Since purchasing it, I have experienced several issues.

One very annoying problem is that Emby “forgets” the key about once per day. I log in and it tells me to purchase Emby even though it is already activated. When I click on key management, it just shows a spinning circle in the middle and never loads, although the license key is visible there. The only way I can fix it is to delete the key and enter it again, then activate it. This is very disruptive because it happens about once a day (sometimes it works fine for 2 days), but it is starting to get really frustrating because I cannot watch IPTV. There are no errors in the log file when this happens.

The second issue is that since I started using Emby Premiere, my LG TV (WebOS 25) has a problem when I watch a movie that needs transcoding: the TV exits the movie during playback and displays a message saying it exited due to memory usage. It does not exit the Emby app, only closes the movie. If I delete the key and use the free Emby version, this never happens. There is no error code in the log file here either. I also tried setting hardware encoding to “No” (disabled it), but that did not solve the problem.

So since using Emby Premiere, I have had more issues than before. Currently I am using a VDS (Ubuntu 24 server), and I do not use any proxy or VPN on the server. These are the two main problems I am facing.

Devs will still want to see server log for when you check the key and get spinning circle.  May want to check the browser console for errors also as it would point to a communications issue with the admin server.

You will also want to open a new topic for the client issue in LG section.

Browserlog.txt  Here are all the necessary files.

That server log does not contain a validation attempt for the key but it is FULL of network errors.

Do you use a proxy or security software?

[SkyNetWhale 0]

Hello.

There is no proxy, no VPN, and no firewall. All ports are open, and it’s a completely fresh Ubuntu 24 installation with no extra settings. Yes, as I mentioned, there is no error code for this—only an error in the browser’s developer tools saying it cannot connect to the API.

An additional detail that might help is that when I previously had a monthly subscription to Emby Premiere, it never did this and it did not forget the key.

I wonder what this error is?

Have you separated you network into different vlan's?

Using something like adguard, pihole the could interfere?

It is only related to DLNA.

[Luke 42077]

Is the machine connected directly to the internet without a router?

[SkyNetWhale 0]

Most likely yes. It’s a VDS server from the provider Netcup.

[Luke 42077]

OK then you probably just want to disable all dlna features on it as all as the automatic port mapper in network settings.

I did what you suggested: I deleted those plugins and restarted, and now there is no error in the log. However, I entered the key about 6 hours ago and it was still working before I removed the plugins. After deleting the plugins, the license was still there as well.

Now I checked again and it has forgotten it once more. It just shows the spinning circle. So unfortunately that was not the cause, the problem is still happening.

[Happy2Play 9780]

Devs would have comment more as only thing per logs that stands out is browser console as server log is not showing anything unless a new log shows something different.

HI, where exactly does this happen?

[SkyNetWhale 0]

The errors can be seen in Chrome DevTools. It clearly shows that, for some reason, it does not allow a connection to the Emby Admin service. I’m seeing these three errors:

https://mb3admin.com/admin/service/registration/getStatus → 401 (Unauthorized)

WebSocket connection to wss://mydomain/emby/embywebsocket?api_key=xxxxxxxxxxxxxxxxxxxxxxxxxxxxx failed

Are these incognito tabs by any chance? That should be OK, I'm just curious. Thanks.

No, this is not incognito mode. And by the way, at times like this, every device that is connected to Emby shows a message saying that I should purchase Emby. This situation is very annoying, and I have already tried everything, but nothing helps.

[Luke 42077]

Should those devices be able to reach our admin domain? Can you think of something you might have that could be blocking it?

For now, I have no idea what could be blocking it. The firewall is not enabled, Nginx is installed on the server and there is a website, but on a different domain. n8n is installed and a few Telegram bots as well, but I do not think they are the problem, because when I was using the monthly Emby subscription, this issue never occurred. At the moment I can reach the Emby admin page from all devices. If it “forgets” the key again, I will check whether I can still connect to it at that time.

They can reach the Emby admin domain. I have noticed that this license issue occurs when it is the weekend and all my family members are using it on multiple devices. On weekdays, when it was only used on a single device, it did not forget the license. In total, 5 devices are actively using it.

Hi, did you find anything related to this?

Szia, találtál valami ehhez kapcsolódót?

Unfortunately, I couldn’t find anything. For the past few days I’ve been the only one using Emby, and it still forgets the key. Now it happens almost every day. I’m not changing anything on the server.
I reinstalled the server, which was a lot of work, but the situation is exactly the same. It’s very annoying at night when I want to watch IPTV and my phone isn’t with me, I have to go get it just to refresh the key again.

[Luke 42077]

OK please email billingsupport@emby.media. Thanks.
