Login EX: encountered a communication error

[Jacob_S]

Hi @MTBuilder

Thanks for reaching out. Last week we made a security change to our API meaning we will no longer accept connections using TLS1.0. As @Triboss has said, you will need to update the SDK and ensure you are using TLS1.1 or greater. 

Here is a link to our blog post which has more information on this - http://myobapi.tumblr.com/post/177017431449/tls10-no-longer-supported

Thanks,

Hi,  you need to update the SDK, not the addon connector:

https://www.nuget.org/packages/MYOB.AccountRight.API.SDK/

Hi TrevorAH

can you please advise how to get the version of the connector,

2018.1.4 installer only contains the connector version 2.21.6556

[TrevorAH]

Upgrading the AccountRight API from 2016.2.99 to 2018.1.144 fixed this for us.

My add-in has started failing today with the same error message. I'm investigating this too.

I'm guessing these errors are related to the TLS change:
