Auth for Rest API issues

[CommunityMember123802]

Hello,

I have recently started to recieve the error "The underlying connection was closed: An unexpected error occurred on a send." when trying to authenticate with the REST Api. This code worked fine last week and now it's failing. I am using RestSharp/C#, can anyone see what my issue is? I don't believe that I have changed anything....

Hi,

Are you using 2.0 API or 1.3?

Hi,

did you try to login directly in the Anaplan home page with that user/pass?, maybe it expire

Sadly, the account is fine. And yes, I did check. That is why this is so frustrating.

Did you find a solution?

I'm having a similar issue. using api 2.0

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

Script works from UI but not when called from Informatica.

Research leaning toward tls issue, no success with the suggestions around forcing tls version.

[CommunityMember123802]

Yes, I did.  Check the project that is calling the Anaplan REST api and make sure that compiling for at least .NET 4.6(?). The issue is with the TLS version, <4.6 is using the older TLS version. It's not a verbose error, and needs some digging to find the root cause.

My issue solved. I had to add -Proxy to the failing Invoke-WebRequest statement. Due to this being a service account, policy will not allow updating the IE settings directly.

Try something like this at the beginning of your method:

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12 | SecurityProtocolType.Tls11;

This appears to be an issue with the .NET web request rather than an Anaplan thing.
