ios - Temporary nw_socket_connect connect failed after delete request -


i have table view, calling function deletes entry remotely after deleted in table view. however, after delete entry , navigate away view, 20 seconds after, navigating table view gives me following error:

nw_socket_connect connect failed: [64] host down

the other data being requested on table view being loaded correctly, know host not down. here code.

    let url:url = url(string: urlstring)!     let session = urlsession.shared      var request = urlrequest(url: url)     request.httpmethod = "delete"      let task = session.datatask(with: request urlrequest) {         (         data, response, error) in          guard let data = data, let _:urlresponse = response, error == nil else {             print("error")             return         }          let datastring =  string(data: data, encoding: string.encoding.utf8)         print(datastring)      }     task.resume()

this code called in:

tableview(_ tableview: uitableview, commit editingstyle: uitableviewcelleditingstyle, forrowat indexpath: indexpath)

any advice appreciated!
