Other Vivox Undocumented Error

Before the weekend, the login was working fine for Vivox. Now, I receive these errors:

<BeginGetConnectorHandle>b__0: vx_req_connector_create_t failed: VivoxUnity.VivoxApiException: (11175)
at VivoxUnity.VxClient.EndIssueRequest (System.IAsyncResult result)
<BeginLogin>b__0: BeginGetConnectorHandle failed: VivoxUnity.VivoxApiException: (11175)
at VivoxUnity.AsyncResult`1[T].get_Result () [0x0000e]
Error: (11175)

It is still functioning in that I can hear my partner when in multiplayer mode and he can hear me, but I'd like to resolve the new errors. I've seen the same issue posted on the old Vivox Forum, but its "resolution" was that it was an internal error and Vivox remedied it.

 

Since roughly the time when this thread was created the Overwatch voice chat which also uses Vivox is broken for me and many others. The game just says "Voice chat error 11175" once and never joins any voice chat. Asking Blizzard support is futile and just results in generic copy/paste troubleshooting that doesn't seem to help anyone.

I was looking for any info/solutions and found this thread which looks potentially related. The Overwatch log (relevant portion included below) also indicates a connection problem. I've tried using some VPNs to rule out router/ISP issues but that doesn't help.

Is there any info to be had what exactly this error 11175 means so I can maybe troubleshoot the issue? Or something that can be done to reverse whatever broke it in the first place? Overwatch voice chat was working fine for all the years prior to this.

This is ongoing and hasn't been working at all for many months. Initially when it started the game would give you a big error 11175 message as soon as the main menu appeared. At that point there is no voice chat to join so the game is just pinging or authenticating to the vivox server.

Blizzard must be aware of the issue because 1-2 months ago the message was semi-hidden and is only seen under certain circumstances. For me I must have auto-joining of voice chat turned on in the game options, otherwise I'll never see the message. If I do have it on, when I join for example the training room (which will have voice chat) I usually see the message but not always, which kinda feels like someone "solved" it by making the error mostly disappear so their support can keep sending everyone to fairytale troubleshooting land.

The game will only ever show the error once and note "#=[VC] Error displayed to user 11175" in the log file. Speaking of which, probably few people know there's a log at all and that it holds the real info you might want to know, like how every new match the game tries to connect to the VC and fails with error 11175. And that it does successfully initialize the correct input/output devices prior to that. If VC would work you'd get a "X players in voice chat" text in the game-chat, but that never happens anymore.

Indeed nothing changed about my client PC so it was almost certainly a bump in the vivox client/server version, but there must be something I can do to make my client work with it again now instead of crossing my fingers and hoping for the next version. Incidentally I even tried replacing the game's vivoxsdk.dll with different versions but you can probably guess how that went (no I don't want to send a crash report).

This is how an in-game error looks like but in this case instead of "[3]" it says "[11175]". The description text is the same but misleading and just a default. As I explained you never join a voice chat so you couldn't be "removed".

 

Some days ago Overwatch had a notice in the launcher that they would do voice chat maintenance for a few hours during which vc will be unavailable.

This error still persists however as of right now.

 

The issue persists after Overwatch downgraded to the Overwatch 2 client.
