context deadline while posting notification through API https:///dm3p.notify.windows.com?token=xxx

Question

got many timeout when using wns for push.

from api https:///dm3p.notify.windows.com?token=xxx

I have been using this function for a year without any problems. This timeout problem has occurred since around 9:00 (utc+8, china) this morning. How can I contact the R & D staff to deal with it? When is it expected to be restored?

example

Post "https://dm3p.notify.windows.com/?token={my token}": context deadline exceeded (Client.Timeout exceeded while awaiting headers)> req=&http.Request{Method:"POST", URL:(*url.URL)(0xc0d8a8e3f0), Proto:"HTTP/1.1", ProtoMajor:1, ProtoMinor:1, Header:http.Header{"Authorization":[]string{"Bearer {my ak}"}, "Content-Type":[]string{"text/xml"}, "X-Wns-Requestforstatus":[]string{"true"}, "X-Wns-Tag":[]string{"c9b6cef39c0d5cae"}, "X-Wns-Ttl":[]string{"28797"}, "X-Wns-Type":[]string{"wns/toast"}}, Body:io.nopCloserWriterTo{Reader:(*bytes.Buffer)(0xc08fa6c6c0)}, GetBody:(func() (io.ReadCloser, error))(0x7a3ea0), ContentLength:1610, TransferEncoding:[]string(nil), Close:false, Host:"dm3p.notify.windows.com", Form:url.Values(nil), PostForm:url.Values(nil), MultipartForm:(*multipart.Form)(nil), Trailer:http.Header(nil), RemoteAddr:"", RequestURI:"", TLS:(*tls.ConnectionState)(nil), Cancel:(<-chan struct {})(nil), Response:(*http.Response)(nil), ctx:(*context.valueCtx)(0xc08fa6c450)}

Hi @景轩 王
Thanks for the question and using MS Q&A platform.
 Increase Timeout Settings: Adjust your application's timeout duration to a higher value to prevent premature timeouts.

 Verify Network Connectivity: Ensure a stable network connection to avoid timeouts when connecting to WNS.

Validate WNS Endpoint: Check that the WNS endpoint URL is correct and accessible using a browser or tools like curl.

 Monitor Server Load: Verify if WNS is under heavy load or experiencing outages by checking Microsoft’s service status.

Analyse Logs and Responses: Review logs for error messages and confirm the correct format of headers and payloads.

Implement Retry Logic: Add retry logic to handle transient errors, ensuring successful notifications even after initial failures.
