Is there a notification for android talk v23.0 when you click the self test button at the bottom of "Settings - Advanced - Diagnosis" ?

Can you share the diagnosis report here?

Below is the diagnosis report:

Push notification sent successfully

The notification appeared, but Nextcloud 32 and Talk v22.0.9 are installed.

Could not send notification to push server [GuzzleHttp\Exception\ConnectException]: HTTP/2 is supported by the cURL handler, however libcurl is built without HTTP/2 support.

During the test, push notifications do not come.

Can you check if it works again, when you remove the following line:
https://github.com/nextcloud/server/blob/7c526b4de33a7f5c29e3d84bf4782bb269d977f5/lib/private/Http/Client/Client.php#L60

RequestOptions::VERSION => '2.0',

Also, which PHP version, and libcurl are you using?

[Valdnet]

After deleting RequestOptions::VERSION => '2.0', I receives the information:

Sorry, an error occurred: expected 624 bytes but received 708

PHP version: 8.2.9
cURL Information: 7.75.0

Can you try to remove https://github.com/nextcloud/server/blob/7c526b4de33a7f5c29e3d84bf4782bb269d977f5/lib/private/Http/Client/Client.php#L62 as well?

[Valdnet]

After removing the lines:
Prefer HTTP/2 globally (PSR-7 request version)
$defaults['curl'][\CURLOPT_HTTP_VERSION] = \CURL_HTTP_VERSION_2TLS;

The notification test passed. The notification was displayed 👍 .
What is cause?

[SystemKeeper]

Thanks for the confirmation.
Where is curl coming from in your case? curl version 7.75.0 was released on February 3 2021, so it seems quite old? I assume it's a system package?

I created nextcloud/server#58528. I am not sure if it's really an issue, since I'd assume that HTTP/2 support should be quite widespread nowadays. So you should check if you can update libcurl on your system.

Yes, this is the system package and my hosting provider.

I created nextcloud/server#58528

Thanks.

Since it’s unrelated to talk android, I would close it for here for now.
