Network configuration issue iphone 17

I was at home and went outside when i got the error message "network configuration issue. looks like DigiCert TLS RSA4096 root g5 is the wrong ssl certificate. this could mean someone is tampering with your device or network. please try another wifi network or contact your it admin for help."


I did a quick search and found an answer where i had to delete the wifi network and add it again. this appeared to fix the issue however 2 days later i am working outside in another location and i have a bad signal so i enable and then disable airplane mode and the same error message pops up.

I have an iphone 17 with the latest software.


Any recommendations?

Hi there


Please try this


  • Check for VPN or Management Profiles: Go to Settings > General > VPN & Device Management. Look for any unknown configuration profiles, MDM profiles, or school/work profiles left behind and remove them. 
  • Check Certificate Trust Settings: Go to Settings > General > About > Certificate Trust Settings and verify whether any newly installed third-party root certificates have full trust enabled or need to be cleaned up. 
  • Reset Network Settings: If the error keeps recurring, go to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings. (Note: This removes saved Wi-Fi passwords and cellular preferences, forcing a clean slate).
  • Avoid Unsecured/Captive Hotspots: If the warning only pops up on specific public networks or carrier hotspots (like public transit Wi-Fi), those networks may be using misconfigured captive portals or outdated intermediate certificates.
