The SSL issue I'm having with the subdomains of aerolla.net and aerolla.net

[windprince]

Hello,

I wanted to address the SSL issue on my website. The problem exists on my website with the address https://aerolla.net

The said website can be accessed smoothly on many devices, but it fails to open on some devices.

I am experiencing this problem on some devices as shown in the screenshot below:

When I checked the address https://aerolla.net using the website https://www.sslchecker.com/sslchecker I received the error message “Vendor signed: No SSL is not trusted.” I would like to point out that this error is not present on other domains hosted on the server where I host my aerolla.net domain (all domains hosted on the same server have the same configurations. Additionally, I tried switching servers and panels to a different server using Cloudpanel instead of Plesk, but the result remains the same, and I still encounter same error on some devices).

The SSL mode is set to “Full.”

The same issue applies to the https://r.aerolla.net/ address (example address: https://r.aerolla.net/w.php?dl=k1Mfn441h3z3lfm&lang=en).

I cannot understand the source of this problem. All of my domain addresses are associated with Cloudflare and have the same server and configuration. However, I am experiencing the issue only on the https://aerolla.net address.

Sorry for my bad English.
Best regards.

The SSL mode is set to “Full.”

Full is not safe, you should use Full (strict)..

Why you should choose Full Strict, and only Full Strict

Unencrypted & unverified connections Imagine you open Paypal and suddenly get that warning [image] Would you continue? Probably not. For decades leaders in IT security have advocated that people upgrade their sites from unencrypted HTTP to secure HTTPS. And for a reason, everything you send via an HTTP connection is sent in plain text and can be intercepted at any point between you and the server. Equally, you’d probably not proceed if you got such a warning, right? [image] That’s when th…
