SSL problem on mobile

Hello,

From the 2 October, I can't reach my site on mobile(ios and android), but all is ok on desktop.

I get SSL error on mobile as you see on my screenshot! someone can help me please?

please help!

What is the domain ?
Looks like something wrong with you SSL certificate or instalation
It should not be showing the certificate request contents ?

www.krokoo.com
The problem is only on mobile

tried both Safari and Chrome
Works fine on my mobile

This is strange, I clean my cache and try again, don't work on chrome Android, also on safari iOS, I check my system and it's up to date 16/09/2021!

Maybe you need to update your system to see the bug.

I updated to iOS 15.0.1 still can not see any issue

Thank you for your repley Yidna!

I check on woorank.com and I see this bug:



Also I check the url  and I find that the 'Additional Certificates' expired 8 days ago (this is the date I started having this display problem on mobile)

Ps: I did a test, and the site is ok for some mobiles, and not for others!
Any solution please?

Thank you!

I dont know what the Additional Certificates (if supplied) are
But yes if they are expired and if they are used
They probably need to be renewed
You could check with the SSL Certificate provider

I find that One of the root or intermediate certificates has expired (9 days ago).
Who should solve this, my web host?
