even i used EVC.. it took a minute to accept.. once u get error message try again.. try in the morning..best time to submit.. my application was accepted in the morning.. i told my friend to do the same thing.. n he also got success.. may be its just a coincidence.. but try it.. hope u get success..
my first try was on 12th july in afternoon.. but got error after 20 min. then i checked all my details of PAN and Aadhar.. then after 1 hour again submitted same application.. again got error.. then 3rd time i removed my fathers middle name.. but again got error.. 4th time i removed Aadhar card n fathers middle name.. again got error.. my 5th try was at night around 10 pm.. without aadhar n middle name.. n again same error.. then i give up n thought to try in the morning.. next at 10:15 am i again filled aadhar number in application and submitted.. luckily they accepted my application.. So try multiple time in day.. make sure that details of aadhar no n pan no is matching.. also sometime try to submit without aadhar.. Sorry for long post..
