Visvesvaraya Technological University, Belagavi — EDDTS OTP Verification Issue Mobile Number Validation Failed

I am unable to verify my mobile number on the VTU eDDTS portal.
Although I am entering the correct OTP, the system shows it as incorrect and there is no option to resend OTP.

Details:
Name: Ghouse Khan
USN: 3KB16ME016
Registered Mobile Number: [protected]
Email ID: [protected]@gmail.com
Issue: OTP verification error / no resend option

Kindly reset OTP validation or allow mobile number re-verification at the earliest.

I'm carrying out this process for degree verification process.
