See captcha code is a verification code of the user. Either the user is a person or an automated system to confirm that captcha is used. There are numerous kind of captcha's such as Image type where you have to select the images which are asked in the question, there are alphanumeric captchas which you need to put by observing them. Sometimes many people confuses between the upper case letters and the lower case letters. So for that I would recommend you to put the captcha very sincerely and hopefully you will be able to log in.

Hello,

Hope you are doing good.

Well, If your CAPTCHA isn't being accepted, the problem might not be with you reading wrong sometimes it do happen we make mistake by understanding a small alphabet with a capital one or your typing — the code might simply have expired. If you open a page and don't submit your entry form right away, your CAPTCHA might be invalid. ... Many CAPTCHAs have an anti-hacking feature that causes them to expire after a few minutes.

oR, there might be some issue with the website try refreshing it. The least problem can be your internet connection, if it's slower or not working.

I hope I've cleared your doubt. Ask if you have any further questions.

Best wishes ahead.
