I am using DevOps 2019 As part of the domain migration we have changed our Devops URL from https:\domain.wireless.com to https:\domain.wire.com
After the URL change, all the build agents stopped working. When the admin console is launched and tried to send test mail I see below:
Exception Message: The underlying connection was closed:
An unexpected error occurred on a send. (type WebException)Exception Stack Trace:
at System.Net.HttpWebRequest.GetResponse()
at Microsoft.TeamFoundation.Admin.Console.Models.DlgSendTestMailViewModel.SendEmail()
Inner Exception Details:
Exception Message: Unable to read data from the transport connection:
An existing connection was forcibly closed by the remote host. (type IOException)
Exception Stack Trace:
at System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size)
at System.Net.FixedSizeReader.ReadPacket(Byte[] buffer, Int32 offset, Int32 count)
Need some assistance on how to resolve such issues.
