On-Prem Connector discovery: Connection attempt to x.x.x.x:443 failed

[Tava]

Hello, I did fresh install from version 3.9.26 to hardware redhat 8.7. No complains and I can access GUI. 

Port between linux and netapp are opened for in/out. I have checked that port 443 is open to my netapp by telnetting to it from linux. It answers:

telnet x.x.x.x 443

Trying x.x.x.x...
Connected to x.x.x.x.
Escape character is '^]'.

When I'm adding that netapp to my environment, I get :

Discover On-Premises ONTAP Failed.Show Less

Connection attempt to x.x.x.x:443 failed

I can access this netapp system manager from that linux via browser with https. Same account and password (admin-levels).

What could be wrong?
