Firefox SSL Issue

When I try to open my website using Firefox it gives me a security error but when I try it with Chrome there are no problems. There is also one odd thing I've noticed. When I check the SSL Certificate of the website on my Firefox it shows ZeroSSL but when I check it on Chrome it shows Let's Encrypt.

My domain is:

I ran this command: N/A

It produced this output: N/A

My web server is (include version): N/A

The operating system my web server runs on is (include version): Linux

My hosting provider, if applicable, is: guzelhosting

I can login to a root shell on my machine (yes or no, or I don't know): I don't know

I'm using a control panel to manage my site (no, or provide the name and version of the control panel): cPanel 100.0.11

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot): N/A

My Firefox shows Let's Encrypt.

Your website looks fine to me: SSL Server Test: (Powered by Qualys SSL Labs)

And all your zerossl certificates are expired: |


Yeah I just closed Firefox and opened it again and it got fixed, the thread can be closed. Thank you.
