API /session v3 no longer works



Hi, I have been using the REST API for some months now successfully and as of this week it has stopped working. 

I am trying to login to my demo account. I receive the following error in my app and also on the API companion. 


V2 of the /session API works fine with the same username, password, api key etc.  





Content-Type=application/json; charset=UTF-8

Accept=application/json; charset=UTF-8

X-IG-API-KEY=my api key



    "identifier": "my username",
    "password": "my password"



HTTP 401

status: error

content-length: 50
content-type: application/json


    "errorCode": "error.security.oauth-token-invalid"

Had the same issue. I emailed the helpdesk and they said 


That is a known issue that our team is currently investigating.  You  can reference

INC0761055 should you need an update on it.

I have the same issue, started yesterday evening:

trading_ig.rest.IGException: HTTP error: 401 {"errorCode":"error.security.oauth-token-invalid"}

I run everything via git/container and therefore  confident I have not changed anything.

I do run multiple sessions (3x) using the same account, wondering if this is now being stopped.

I have not had a single issue for more than a year.

I had this issue yesterday actually, The API needs to be better documented. It seems to be abandoned but VERY helpful and useful for some of us. The only way I find out is by literally looking at the JSON responses as the documentation is out of date.

Same for me, it stopped working this week with no changes to my code base. 
I can sort of get the api companion working at labs.ig,com but i can't for the life of me figure out how that can work by my code doesn't.
