Warning 400 there was a problem communicating with the Learning Record Store
Hi All
Has anybody seen this error when launching a Captivate 8 course from an LMS. It doesn't do it on my work pc but it does on my client's. The full message is this

Our LMS provider suggested that I add a number of email domains to the client's whitelist which they have done, but this hasn't sorted the problem. It happens on launch only. If they click OK it will let them proceed but am sure that's not good.
Any advice on this would be most welcome. There was a previous question on this back in May but no answers on it.
Many thanks
Janet
