We have found that this issue appears to affect older 2012 servers, but please do check even if your server is not 2012.
If this is the case with your server or you're on an older version of Proclaim it may be worth checking to see if when you click on the grant authority button in VAT Management if you are getting this error in advance of the submission deadline.
You will also get this error if you try to browse directly to the HMRC login page from Internet Explorer on your server.
To test the system to see if you have this issue you can:
Open Internet Explorer.
Click Sign in.
If a box opens for you to enter a gateway ID and password then the client will be able to submit.

In some cases clients have been able to submit from a different server where the HMRC Login page opens, or if you have Proclaim installed directly on a PC or Laptop where you can browse to the HMRC login page in internet explorer then you will be able to submit from there.
We would urge you to look at upgrading to our latest version of Proclaim that uses Microsoft Edge as you will be aware that Internet Explorer is no longer supported.
