If your IT refund bank account pre-validation is failing with a 'technical issue with bank' error, it's likely due to a mismatch between your bank details and PAN, or a server problem. Mismatches in your ITR filing don't affect pre-validation. Try re-submitting your details, and if the issue persists, it may be a temporary server problem.

I have added the Bank details in the pre validation but the request is in “BANK ACCOUNT DETAILS VERIFICATION FAILED BECAUSE OF TECHNICAL ISSUE WITH BANK” status for a long time. How to get it validated ?
