Very slow app and video start

[donniedarko83 6]

Hello,

The Android TV app starts very slowly for me. Sometimes it takes 20 seconds to get to the home screen. It takes a good 30-60 seconds to start a video. Loading images on the home screen also takes longer. However, this only happens with a remote connection, not on the local network. I have tested this with various devices.

I would naturally assume that it is due to my internet connection. However, when I use the normal Android app or the web browser, everything works perfectly without any waiting time.

I had to renew my SSL certificate yesterday. So I suspect there must be a connection here. But what is it? It works fine with the other apps. I've already uninstalled the app on the devices, but that didn't help either. Can anyone help me here?

I had to restore my old SSL certificate because nobody could connect to my server using the Samsung app. My old certificate is still valid for 30 days, so I used this version. But I don't understand why it doesn't work with the new one. Any ideas? It's from the same provider.

What SSL provider ?

Samsung has some issues with Lets encrypt.

Where samsung would reject some but not others.

[donniedarko83 6]

I am using PositiveSSL (Sectigo Limited). It is strange to me, that the old one still works. But not the new one 

[Neminem 1518]

Hmm yes curious.

I would call there support about there certificate and samsung issues.

Does it work via other clients simple webui test.

[donniedarko83 6]

No issues with other clients, beside the Android TV app. I will try to contact the support from PositiveSSL

[Neminem 1518]

Yes there must be a issue with the cert. 

It might not be signed correctly, do you see any difference if you look at the cert's via browser ?

There might be some clues.

Hi.  Can you try searching for our standard android app (Just "Emby" on Amazon and "Emby for Android on Google) on the same device's app store and see how that compares?

Thanks.

The only difference I can see is that the new certificate has this CN: Sectigo Public Server Authentication CA DV R36

The old certificate has this one: Sectigo RSA Domain Validation Secure Server CA 

Everything else seems to be the same (except the valid date)

With the standard android app I have no problems at all. But I cant install the standard android app on the samsung TVs. Only on the shield, firetv stick etc

That will not work on Samsung TV app, there is something strange with that cert.

I assume its the cert since samsung has problems with some cert. providers.

Samsung might not have certified / allowed there new CN, Company Name.

This could be it. I will have to try another SSL provider. Maybe Comodo SSL? 

[Neminem 1518]

I found this topic, they believe that ZeroSSL, I would try with that first  

[donniedarko83 6]

I switched from Zero SSL because it was 10USD per month. With Positive SSL it just about 7USD per year! And I just used the three month test period from Zero SSL so far

[Neminem 1518]

Ok so

Zero SSL works

Positive SSL does not

But now you know what to look for

What is everyone else using? I cant be the only one? And I dont get it why the Android TV is so slow with the new Certificate. If I connect with the shield am message appears for about a second "unable to connect to server" and then all of a sudden it connects anyway. This is taking about 20 seconds before the home screen appears.

[Neminem 1518]

Have you tried restarting the server after new cert. ?

I use let encrypt but have no users with a samsung

Edit

Did they restart there tv's / devices and try again ?

Edited August 17, 2025 by Neminem

[donniedarko83 6]

Yes for the server and the TV's. No change. Let's see what the support from positive ssl will answer me

I use Let's Encrypt as well as Caddy automatically sets that up for every route.
It works perfectly fine with Samsung clients, at least the family i have connecting to my server.

 

[donniedarko83 6]

Okay thank you. I will look into Caddy and Lets Encrypt then. I hope this is not too complicated. I already found a docker version of it. 

[Neminem 1518]

Or look into NPM also docker it does the same.

Never used Caddy, so can't comment on that.

Thank you. That one looks also very promising

NPM is a tried and tested industry standard and has a gui and is relatively easy to setup and understand.
While Caddy does not have a gui i will argue it's even easier since all you have to put into the config file is something like this:

---

{
    email your@email.com
}

your.domain.com {
    reverse_proxy embyeerver:8096
    header {
        X-Robots-Tag "none"
    }
}

---

It will automatically handle the rest.
You can't go wrong with either of them.

[donniedarko83 6]

Thank you for the example config file. I can also choose from various presets like this. Would that be easier? What should be entered in the Proxy To: field? C
