We’re trying to use the SMTP feature within Octopus (running 188.8.131.522) but we’re running into an issue regarding certificates. We receive the following error message and I’m just unsure where to start:
The remote certificate is invalid according to the validation procedure.
System.Security.Authentication.AuthenticationException: The remote certificate is invalid according to the validation procedure.
at System.Net.Security.SslState.StartSendAuthResetSignal(ProtocolToken message, AsyncProtocolRequest asyncRequest, Exception exception)
at System.Net.Security.SslState.StartSendBlob(Byte incoming, Int32 count, AsyncProtocolRequest asyncRequest) …
The error message refers to the “remote” certificate but does that imply the mail server from which SMTP is attempting to use, or is the Octopus Server’s certificate the “remote” one from the mail host? We have a valid certificate for our Octopus server. Any thoughts or suggestions would be helpful. Thanks!
