Invoke-WebRequest : The underlying connection was closed: An unexpected error occurred on a send

[svc-jirabackup]

Hi,

I`m trying to use this script for backup

https://bitbucket.org/atlassianlabs/automatic-cloud-backup/src/master/backup-jira-api-token.ps1

as soon as I reach the section
# Wait for backup to finish

after several successful attempts to check the status, I'm starting to get an error when I send any request to the API.

Invoke-WebRequest : The underlying connection was closed: An unexpected error occurred on a send.

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12 - not resolve this problem.

and this also

add-type @"
using System.Net;
using System.Security.Cryptography.X509Certificates;
public class TrustAllCertsPolicy : ICertificatePolicy {
public bool CheckValidationResult(
ServicePoint srvPoint, X509Certificate certificate,
WebRequest request, int certificateProblem) {
return true;
}
}
"@
[System.Net.ServicePointManager]::CertificatePolicy = New-Object TrustAllCertsPolicy

Thank you.
