I uploaded new cert, now i have my fqdn when i try to connect to my guest network.
In mobile device all is correct, but windows display warning about unsecured data sending. I have set use https in capative portal, windows still use http. Can i fix it or force to use https?

for instant APs, you need to upload the new wildcard cert in pem/cer or crt format
I generally use pem with no issues. The pem format cert should have the full chain
The last section of the pem format should include the private key.

Hi,
I have AP 505 with software 8.11.1.0. I am fighting with hotspot system. I have external captive portal, it works fine. But i have problem with redirect to securelogin.arubanetworks.com all clients devices report this doman as unsecured, and its true because certificate on this site are selfsigned.
I will setup own securelogin domain like securelogin.mydomain.com. I have wildcard certificate for mydomain.com. I try to add my cert in Maintenance>Certificates and i have fail. Still I see Convert certificate error. For my cert i have 3 files: certificate, private key, CA cert. Also i try to convert my files to pkcs12 cert, its still does not work.
How can i setup securelogin.arubanetworks.com for my captive portal?
