Problems with certificates [split topic]

Hello prallo,
As per team they resolved the issue,Please re-check and confirm.

link: download.comodo.com not acessible (problem SSL) here in Brazil;
link: cdn.download.comodo.com is normal :-TU

Hey liosant, Are you too facing this problem?

Yes, my problem is not connection with

download.comodo.com

see picture in attachment

[at]Dharshu

No, problem is still there !!!

When I change the server in CIS to cdn.download.comodo.com it works !

Can I leave the server to cdn.download.comodo.com or do I have to change it back to download.comodo.com ?

By the way, I am in Thailand.

I cannot reproduce the latter with IceDragon and various other browsers. Does the same problem happen with other browsers? Please test this the next time before posting. It is basic troubleshooting we shouldn’t be asking an experienced user.

Can you access the Comodo forums without getting that notification from your browser? Does it only happen with that or other download links?

@prallo, Okay.

I tested it in Firefox, Chrome, Internet Explorer and Microsoft Edge, all newest versions.
All browsers report 404 Not Found error with the page download.comodo.com.
The page cdn.download.comodo.com works fine in all browsers.
I am in Thailand if that helps.

https://download.comodo.com/

Does not work for me either, it gives “404 Not Found”.
Checked with Firefox and with Tor Browser with many different circuits so request origin does not matter.

This problem was solved earlier, but recurs again.

I can update using “cdn.download.comodo.com”, but cannot complete a new installation using the online installer.
I cannot access cdn.download.com.com through browsers with an error 403 “You don’t have the user rights to view this page.”

:-TU
NOTE: the problem is generated if two connections exist, for example, link:

http://download.comodo.com
https://download.comodo.com
... Maybe browsers have improved their security systems and not allowed mixed connections or download.comodo.com not accessible

please elaborate. What can I do to access these sites?
However, the update function in Comodo firewall can access through “http://download.comodo.com” but not “https://download.com.com”. This seems like a certificate issue , which has happened before.
This failure really discourage potential new users of Comodo Firewall. Imagine, you follow the instructions to download and then try to install but fail. What will this do to the potential new users?

Try to re-cap the problem:

  1. add this line to the host file : 178.255.86.194 download.comodo.com
    a. Running the installer will get
    " Failed to initiate the installer. Please check your Internet connection …
    Error 12037 . The date in the certificate is invalid or has expired.

b. Running update in Comodo firewall will get

Error: 0x80072f05 - The date in the certificate is invalid or has expired

  1. a. If the “https” is changed to “http”, the update will work
    b. if the https://download.comodo.com" is changed to “https://cdn.download.comodo.com”, then :Download websites database" will get an error.

  2. a. Removing this line “178.255.86.194 download.comodo.com” in the host , running the installer will get
    " Failed to initiate the installer. Please check your Internet connection …
    Error 12175 . Content decoding has failed.

b. Running the update will get

Error: 0x80072f8f - Content decoding has failed

  1. Checking my record, it was reported and solved in early June. But NOW it comes back
