IO with two accounts doesn't seem to work

[mtedds]

I have two different properties / accounts. They seem to have the same API key but can be differentiated by the Account number.
Both are on IO.

When I try to set up the second account, it doesn't work and I find the following in the log:

I renamed the original integration but that made no difference. Is there a way to add a second account?

Thanks!
