Looks like your mail provider does not accept your username / password.

P.S.: Are you aware that you are posting your credentials on a public forum?

As @ooxi said, be careful what you post.

It looks like your ID was a gmail address, but you're not connecting to a gmail server. So either your Host setting is wrong, or you are being redirected by your ISP. Either way, this is all covered in the troubleshooting guide the error message pointed you at, which is why it's there.

ok thanks to advising me. Here after i will take care of it.

But im using $mail->Host = smtp.gmail.com;

Well exactly - as the guide says, check that the server you are connecting to is the one you expect - you are asking for smtp.gmail.com but you can see it's not connecting to a gmail server, which suggests it's being intercepted and redirected to your ISP's mail server, on which your gmail credentials will obviously not work. This is why you should never turn off certificate verification.

Note that your own change of certificate has nothing to do wtih this.

So its not a code problem....How to fix this? any suggestion please

Nope, not a code issue, and as such not something we can fix for you. Talk to your ISP, read their docs.

Ok.Thanks for your support.I will ask my hosting provider regarding this
issue

Ick. Is anyone really using POP-before-SMTP auth any more? It's been obsolete for decades. It's irrelevant anyway, since the error here is caused by an entirely different problem.

[Synchro]

Except it's not the right direction - his ISP is redirecting SMTP connections to another server, and that will not be solved by using POP before SMTP, which gmail doesn't support anyway. It might be a solution, but not to _this_ problem.
