[Bug]: Stremio v5 Streaming Server "Error" status and "Stream not supported"

Describe the bug

I have both v5 and v4 Stremio applications along with Stremio Service installed on my PC. About 2 months ago the v5 application stopped playing videos saying "Stream is not supported" and directing for external app. It downloads a .m3u file that I can stream on MPC-HC or VLC just fine. This happens for all content I try to watch from any provider (I use torrent sources). The v4 application, web.stremio.com or app.strem.io work just fine.

What I notice is that every time I open v5 app, it has a yellow banner saying "Streaming server is not available" with an install button that has link to: https://www.stremio.com/download-service. I have this installed and running it doesnt make a change for anything either.

Another thing I noticed in the settings is that default URL http://127.0.01:11470 has a status "Error". I added different ports and selecting any of them gives error as well. The same default URL http://127.0.01:11470 on v4 application settings seem to not give error and the application plays videos internally just fine. Even when I open only v5 app, opening the default URL on my browser directs to v4 shell as seen in this link:
https://app.strem.io/shell-v4.4/?streamingServer=http%3A%2F%2F127.0.0.1%3A11470#/

The issue started around the time I installed Docker in my PC for WSL. However, closing Docker completely doesnt change anything for Stremio v5 along with reinstalling the application itself. I am not sure about if its related at all.

To Reproduce

1. Launch Stremio v5 on a Windows machine (with Docker Desktop/WSL2 installed?)
2. Observe the "Streaming server is not available" banner.
3. Go to Settings > Streaming.
4. Observe the "Error" status next to the local server URL.
5. Attempt to play any torrent-based content; it fails with "Stream is not supported."

Expected behavior

The internal streaming server should bind to the local port successfully, and playback should occur within the v5 application.

Something on your device is blocking streaming server from running. It is impossible to say what as do not have any tools to remotely debug such issues.

I have the exact same problem, stremio 4.4 no worries, stremio 5 doesn't work.
I have adguard installed, so I know its my adblocker/custom dns causing the issue, because when I disable it both versions work.

Nevertheles, it's weird first because only happens in Windows, on Mac no issue even with same adgaurd, and second because I whitelisted all strem.io and stremio.com links and it still happens.
Furthermore, if i go to https://app.strem.io everything is fine but if I go to https://web.stremio.com the yellow banner appears.

Why is the behavior different between stremio versions or why on one web app link is fine but the other no, or why only windows version is affected?
Doesn't make sense to me.

I will go back to stremio 4.4 for now, because I can't live without my adblocker.

Tell me if you need me to test something else, or if I should whitelist something else in my adblocker/custom dns.

Thanks

IF this is your adblocker causig this then only way for you to fix it is to confiture it properly.

I am getting the similar error when deploying the stremio over docker, and running it over web.stremio.com but then im publishing the stremio service over cloudflare tunnel, so not sure - it was working nicely before

Go to your terminal and run:

curl -i "http://127.0.0.1:11470/get-https?ipAddress=192.168.1.23" (replace 192.168.1.23 with your server local ip address)

You’ll get something like:

HTTP/1.1 200 OK
content-type: application/json
content-length: 92
Date: Thu, 20 Aug 2026 21:14:46 GMT
Connection: keep-alive
Keep-Alive: timeout=5

{"ipAddress":"192.168.1.23","domain":"192-168-1-23.519b6502dxxx.stremio.rocks","port":12470}sEdd@localhost:~$

So your Stremio https server address is(in my case):

https://192-168-1-23.519b6502dxxx.stremio.rocks:12470/

This is the only way I could get it to work 🤷‍♂️
