Hello,

We have just renewed our license for “Katalon Runtime Engine (Floating)”.

I am now getting this weird error, under a 400 error on the api/v1/license-keys/activate endpoint:  
“The number of the registered machines cannot exceed the license quota”

I got it both with an old key and a new key.

I got it even after having deleted all the “registered machines” under admin/license\_keys/unlimited\_engine for KRE.

Also, the console tells me that I have “unlimited machine quota”!

What am I missing?

Regards,  
–Michel
