Error adding gateway removed

I am having the error of being able to add a gateway that was previously deleted.

{
“code”: 6,
“message”: “error:pkg/util/store:id_taken (ID already taken, choose a different one and try again)”,
“details”: [

}

Read the error message, think ID =!= EUI.
And if you still need more, search the forum with this error message as this question comes up (almost) weekly so there is a wealth of information available.

It is deeply disappointing that having asked on Slack that you did not follow the advice that I gave which is IDENTICAL to the advice that @kersing has given you.

Please do not contact anyone via private message but put in to action the advice you have been given.
