My State Bank of India Corporate account is disconnected, when I try to connect it asks user/PW/OTP, even after I enter all info, it keeps asking me for the same.

I've come to help connect your account successfully, @boby1.

Let's perform a few browser troubleshooting steps to determine why you're unable to connect your State Bank of India Corporate account to the QuickBooks Online (QBO) banking feeds. 

To begin with, let's try logging into your QBO account and connecting to online banking using a private browser. To use a private or incognito browser, here's how:

• Google Chrome: Ctrl + Shift + N
• Mozilla Firefox: Ctrl + Shift + P
• Safari: Command + Option + P
• Edge: Ctrl + Shift + N

If this works, it means you need to clear your browser's cache so the system can start fresh and you're now able to connect your bank account accordingly. But if you get the same result while using a private browser, let's switch to different supported browsers instead.

I'm adding this helpful article for ideas about the other methods you can start using to get your online banking transactions: What to Do if you See Error Messages or Don't See Recently Downloaded Bank Transactions?

Keep me updated in the comments if you have any other questions other than QuickBooks online banking. I'll be here to lend a helping hand. Take care and stay safe!
