Hi, I am stuck with same error too, Did you find any solution ?
I have recently updated my phone number using Form 8 online and the status says EROLL_UPDATED. When I try to download my eEPIC also it shows my correct phone number as XXXXXXX09 but, when I try to add the EPIC number in the Profile section, it still shows up the old phone number ending as XXXXXX17 and OTP is sent to the old phone number which I don't have.
Error says Mobile number in Eroll is different from Profile section.
Does anyone know how I can add my EPIC number to my profile?
