iPad message "Cannot verify server identity"

I had the same issue, and after searching I found this solution. Go to Settings -> Mail (official Apple mail app) -> Accounts -> Subscribed Calendars. You will find a SPAM calendar added to that folder go inside then delete it from the bottom of the screen

Gettin the same but mine is muluspubli.club how do I get rid of it?

Hello, I have the same issue, but I don’t know where to find calendar subscription. Could you please help?

A commonly exploited vulnerability, as appears to be occurring here, involves your iPad/iPhone Calendar…

The symptoms are your Calendar appearing to have been populated with regular or recurrent events that warn of malware infection - or attempt to prompt the victim into performing actions that will compromise personal data, the device, or your financial information (that will be used to defraud the victim, or perform other financial fraud).

Whilst not a malware infection in the traditional sense, if this exploit is observed on your device, it is highly probable that you were manipulated (via a simple click on a website link) into “subscribing” an additional (unwanted) Calendar(s) to your device - and this unexpected Calendar is exposing unwanted calendar events and sending you unexpected “adverts” or other warnings. 

In some circumstances, as seen here, embedded website URLs may result in Certificate errors when accessed by the device.

If you see this issue, you’ll need to check for what’s out of place...

iOS/iPadOS13 and earlier

Settings > Passwords and Accounts

iOS/iPadOS14 and later

Settings > Calendar > Accounts

Look for an “account” that shouldn’t be in the list of accounts - as this will likely include the Calendar that contains all the unwanted events.

When/if you find the suspect account, tap - then select Delete Account. This should resolve this specific problem in its entirety - although a forced-restart is recommended after removing the offending entries:

Force restart iPad (models with Face ID or with Touch ID in the top button)

If your iPad doesn’t have the Home button, do the following:

1. Press and quickly release the volume button nearest to the top button.
2. Press and quickly release the volume button farthest from the top button.
3. Press and hold the top button.
4. When the Apple logo appears, release the top button.

Force restart iPad (models with the Home button)

Press and hold the top button and the Home button at the same time. When the Apple logo appears, release both buttons.

It is a pop up message about a certificate. It is random in term of apps that trigger this msg.

it only happened to my wife's iPhone 13 but not my iPhone 14 Pro Max or my iPad Pro 10.5.

for me personally it just randomly pops up even if im on my home screen doing nothing

Perfect. Thanks for the tip I had multiple mputerskill.biz entries.....

I HAVE THE SOLUTION!!! Please go to “Mail” in settings and find the option “Account “ then you’ll see your accounts and one more. That account you don’t recognize is the problem. Just delete it and that’s it.

Where, specifically, are you seeing this message? Is this a pop-up message that you see on a particular website, or an error that you see elsewhere - perhaps within an App?

Pop -Up message

impossibile verificare indennità server

ansedwaysi.club

grazie per il supporto

In my case this link: Configure contas de e-mail, contatos e calendário no iPhone - Suporte da Apple (BR)

resolved my problems!!!!!!

• Set up a calendar account

similar issue with different certificate issuer - in my case, it is "ensivecigaretc.club". Started popping up after iOS update to 16.4.1, appears randomly, oftentimes on the locked screen and when connecting to iCloud.

Perhaps if you answer the questions already asked of you in my previous reply, appropriate guidance may be possible…

Without specific information as to where and how you see these messages, it’s difficult to provide the answers that you seek.
