BIG-IQ ASM Security discovery fails

Hi all!

 

I am dealing with a problem when I try to discover an ASM BIG-IP (11.5.2 HF1) into the BIG-IQ (4.5.0 HF1). I get the following error.

 

Status code:401, uri:https://:443/mgmt/tm/sys/provision?ver=11.5.1&em_server_ip=122.36.81.206&em_server_auth_token=..., body:

 

This action will permanently remove this object and its dependencies from BIG-IQ.

 

Does anybody know what it's happening?

 

Thanks a lot

 

Marc
