Invalid SSL Certificate with Hotspot

Hello to all .

I have buy a certificate for my domain . example hotspot.mysite.com

But when i ask from web broswer from mobile example i get invalid ssl certificate .

At the hotspot is check https http chap pap if that helps …

Anyone knows why that happens ?

My ssl is valid for 1 year if that helps . Thanks

Have you import it correctly?
First .csr and the .key

Do you have it enabled under hotspot settings?

Under services do you have the correct cert?

Too many option too little information.

Yes everything is ok . It is possible that broswer/mobile can verify the certificate with the authority ?
