Server identity and connection errors on Apple devices

A bit of iPad and iPhone internet weirdness..,


Hi, a while back I had noticed in our router’s control panel that a couple of our devices were connecting to a website (solarunitedneighbors.org) frequently and even when we were not using the devices. This was a website I used to visit and participate in when I was looking into getting solar panels for my home in 2017. Come to find out I cannot get panels without major roof structure updates - that has unfortunately determined that I will not be proceeding further on that path. I still had the website bookmarked in safari until I noticed the frequent connections last year and began to troubleshoot. The first thing I could think to do was to block the site on our DNS provider NextDNS. That worked… sort of? Ever since then for at least 6 to 8 months when I pick up either my phone or tablet the first thing usually I see is a message “Cannot Verify Server Identity. The identity of ‘www.solarunitedneighbors.org’ cannot be verified.” If I click on details I am taken to the stock “Blocked by NextDNS, contact your administrator to unblock this website.” page which tells me the block I setup is working. But why are my devices trying to connect in the first place?



The next thing I thought of shortly after discovering this was that maybe Safari connects to all your bookmarks for some sort of reason like prefetching or something. Even though that seems totally excessive to me, I took a look and found the bookmark and removed it. So at this point it has been several moths later and I am still scratching my head on this one.


So this only happens on my 2 devices. But at some point around the time of discovery another anomaly began to happen only this happens on my devices and also my son’s phone and tablet and also our Mac mini. When we are using a browser it happens quite frequently that the page will go completely dark and we are interrupted with another message that reads “This connection is not private. This website may be impersonating ‘whateverwebsitewemightbeusing.com’ to steal your personal or financial information.” And 2 buttons Reload and Visit Insecure, both of which refresh the page which can be exceptionally annoying, especially when you are in the middle of filling out a form, or most of the way down a really long page which refresh will start you over at the top.



Anyone been down a similar road and can provide some helpful insight would be a lifesaver (or at least a sanity-saver lol). It knows I’m taking about it so I will end here for now…..

Your may have a subscribed Calendar or a CalDAV or a CardDAV/LDAP account for Contacts or Calendars.



What happens when you click the "Details" on the error popup message (See the Pic below)



The best would be to Delete and Add the email account that is creating the issue.


You may also try changing SSL settings


Settings > Password & Accounts > [Select the Mail account} > [Tape on Account with the email ID} > Advanced > SSL Settings > [Disable]

Click <Account (in Blue)

Click on DONE (in Blue) when exiting in the previous screen




Probably you may have accepted an offer or subscribed for a spam Calendar accidentally. Watch the GIF below to know how to unsubscribe from these calendars. Look for an unknown Calendar on the device under subscribed calendars.




The pic below is self-explanatory if you have subscribed to a calendar.

@SravanKrA Hi, thanks for your time. Clicking on Details shows the following:


I’m using Gmail in my browser to check my main email account so I don’t think the SSL suggestion applies here although the server identity pop up does look similar to my solarunited one.


The second image may be for an older version of iOS. I’m on 26 so I don’t have an option for passwords & accounts I have to go to apps > calendar and this is a little strange here. It says I’m only using the iCloud calendar but when I look at default calendars there are several and I can’t figure out where to remove them since they aren’t listed under calendar accounts.



If one of these is the culprit I’m not sure how to delete it.
