PowerShot SX540 HS help with transferring photos to iPhone

[amyjyoung612]

I have a PowerShot SX540 HS, and Have transferred photos to my iPhone several times.  Never any issues connecting to wi-fi or to my phone.  Recently, when attempting to transfer photos, I can connect to WiFi, then when selecting transfer to phone, it says, open Canon APP on phone, which I do, ... then when trying connect, after a few moments it simply says -  Error Detected.  No explanation as to what the error is or how to correct it.  

Please help.    Thank You.

Try deleting the connection settings in the Wi-Fi setup in the camera and also the connection in the app in the phone. Then set up both again.
