SSL error on an iPhone could be the result of internal iOS issues or interference from the network/router. Internal iOS issues might range from outdated iOS to corrupt OS of the iPhone. The issue arises when an app or a website in a browser shows an SSL error on an iPhone.
An iPhone might show the SSL error due to many factors but the following reasons can be easily called the main ones:
- Outdated OS of the iPhone or Outdated App: If the OS of the iPhone or the problematic app is outdated, then the one’s incompatibility with the other may not let the iPhone’s network modules properly communicate over the SSL protocol, causing the SSL error.
- Incorrect Data/Time of the iPhone: You may encounter the SSL error on an iPhone if the date/time on your phone is not correct as the response server may fail to parse the SSL data packets having the wrong date/time stamps.
- Corrupt Network Settings of the iPhone: An iPhone might show the SSL error if the phone’s network settings are corrupt as the SSL-related modules on the iPhone may fail to load.
- Router Security Product or Content Filters: If the router’s security or content filters (like parental controls) are hindering the iPhone’s access to a required online resource, then that may result in the SSL error at hand.
For developers who are encountering this issue on their websites, make sure the certificate is valid on the server. Also, if your server is using an old SSL protocol, then you may have to reinstall the server’s OS with the latest SSL protocol to clear the SSL error on the iPhone when accessing your web server.
1. Enable and Disable Airplane Mode on the iPhone
A temporary communication glitch on your iPhone may lead to the SSL error and enabling/disabling the iPhone’s Airplane mode may solve the problem as the communication modules are re-initiated.
- Launch the iPhone Settings and enable the Airplane Mode by toggling its switch to the off position.
- Now wait for a minute and then disable the Airplane Mode to check if the iPhone has started to work fine without showing the SSL error.
If the issue is occurring with a particular website, then the incompatible or outdated SSL on the server side could be the reason for the issue and you may contact the support of that website to clear the error.
