[Sanket22]

Not able to send mail using SMTP server by using example vi of SMTP with Gmail credentials. Anybody who recently tried SMTP and face the same issue?

I will use the search function to answer the question:

Yes, this person did. Exactly the same issue: https://forums.ni.com/t5/LabVIEW/Error-363500-Failed-to-connect-to-the-specified-hostname/m-p/416516...

Without having more details it would be hard to help (things like code, which errors you're seeing, etc).

I can say that Google disabled the option to send email using SMTP using the account password at some point and forces people to use 2FA and then you can create a separate app password you can use for your application:

I'm guessing this is your issue, but that's just a guess.
