WinINet timeout (12002) with all online sources on Windows 11 25H2 (build 26200)

Hello Florian,

I'm using Mp3tag 3.35 (64-bit) on Windows 11 25H2 (build 26200).

For several years, Mp3tag worked perfectly on this PC (first under Windows 10, then Windows 11). Recently, all online tag sources stopped working.

Symptoms:

  • MusicBrainz: "Connection error to server: musicbrainz.org" (12002 timeout)

  • Discogs: "Failed to authenticate using OAuth (12002)"

  • Browser access to MusicBrainz, Discogs and oauth.mp3tag.de works normally.

  • Test-NetConnection musicbrainz.org -Port 443 succeeds.

  • curl.exe https://musicbrainz.org/ws/2/ succeeds.

  • TLS 1.2 and TLS 1.3 are enabled.

  • No WinHTTP proxy configured.

  • Updated from v3.32 to v3.35.

  • Fresh configuration does not help.

Could this be related to Windows 11 build 26200 or a recent WinINet change?

Thank you.

In the old days the check whether MP3tag actually goes into the internet was to use Help>Check for new version ...
You should get a message box.
If you don't then MP3tag has no internet access.
You would have to check locally then, why this is the case.

Please check the date and time on your Windows system.
It should be very close to the current world time.

Thank you Ohrenkino. I checked and Mp3Tag has access to the internet.

Thank you LyricsLover. Time & Date are OK.

Have you tried increasing the timeout via File → Options → Networking?

Also, are you on a VPN which might be throttled by Discogs and MusicBrainz?

Hi Florian. No VPN. I tried increasing the timeout to 30s. But I got the error msg after about 10-12s.

I'm using Windows 11 25H2 26200.8737 and I'm not experiencing those timeout issues, so it's unlikely to be related to Windows 11 build 26200 or a recent WinINet change.

@Cubitus Could you please run the following test in a PowerShell command window:

$ie = New-Object -ComObject WinHttp.WinHttpRequest.5.1
$ie.Open("GET","https://musicbrainz.org/ws/2/")
$ie.Send()
$ie.Status

If this results in a timeout or a 12002 error, it strongly suggests that WinINet is malfunctioning on your system.

BTW: What build exactly do you use? My Windows 11 shows version 25H2 26200.8655 (using the command winver.exe), which is a stable, non-preview release updated to date.

I ran the commands and I got a 301 response. I am as well using Windows 11 version 25H2 26200.8655

A 301 result is good (it means "HTTP 301 Moved Permanently" and is the answer from the reached external server).

What about security software in your environment?
Could you disable all your antivirus, firewall and other protection software - just for a test in Mp3tag with MusicBrainz and Discogs?
This would allow us to rule out any influence they might have.

I stopped all Avast agents for 10 minutes. Same error after 10-15". Failed to authenticate using OAuth (1) 12002 time out.

So, are you saying that AVAST is the reason for the blocked connections?

I just say that, even with Avast agents in pause, the problem is still there. That makes me thinking that Avast is not the reason

If you stop AVAST for 10 minutes, and then immediately try to connect to MusicBrainz and Discogs in Mp3tag, does it work? (Connecting with paused AVAST?)

it is exactly what I did.

"I stopped all Avast agents for 10 minutes. Same error after 10-15". Failed to authenticate using OAuth (1) 12002 time out."

Do you have a router with firewall or similar capabilities?

Also, you could try a real API query like

https://musicbrainz.org/ws/2/release-group?artist=410c9baf-5469-44f6-9852-826524b80c61&type=album|ep

which doesn't redirect to the documentation.

No firewall with my router. I only use Avast firewall.

I have just tested your query and it works (even though I don't know exactly how to use the result)
