HTTPS website with cracked padlock in red.
-
When I visit a secure (HTTPS) website, the usual padlock in the address bar of the Morph browser sometimes appears as red and cracked. I suppose this means the connection is not secure. May I ask why and how this happens and how to avoid it?

Hi @ubuntoutou
This is often due to outdated certificates on the server side.
This is the behavior expected by the browser if a website is note compliant to the secure protocol. -
@ubuntoutou Additionally to what AppLee has said, it might also be that the
server certificate was issued by an organization that is not (yet) trusted by the current version of the OS.If you go to the same website on a desktop, what do you see?

@arubislander Thank you arubislander and AppLee. The cracked padlock in red does not always appear like this. Most of the time it appears as a normal locked padlock in black. Here I am talking only about a single website. On my PC with Firefox under Linux, this web site appears with a normal padlock. This web site is my web mail for which I am paying a fee every year. So it is quite a serious breach of security. Could this be a hack directed against the web mail server or even a hack against my home devices?

@ubuntoutou if this were a man-in-the-middle attack directed against your server or against your home router, your phone and your PC would have the same issues. Since you are only seeing this on your phone then the issue is probably only on your phone..
Are you making use of uAdBlock by any chance?

@arubislander Just to clarify:
- I don't run any server. I have no network at home apart from the link between my router and my PC and UT phone. The server I was referring to belongs to the commercial email service provider and may be located in another country.
- I am not absolutely sure that the issue does not appear on my PC. It just happens that I have noticed it on my UT phone. But I think it does not happen on my PC.
- I am using µAdBlock. But is this a problem?
