The provided host name is not valid for this server.

Searching for the literal error message, a practice I recommend which makes better use of everyone’s time, gives https://drupal.stackexchange.com/questions/145286/what-does-the-provided...

I done the https part as I said there is no error that showing on the configuration page for the https thing, but I am still getting this host name error.

I now redirect all the https://abc.com to https://www.abc.com to solve this problem temporary.

It is fairly well documented in settings.php and in the link I posted. No other answer can be given absent more info.

11 months ago more information was asked and none has been provided nor has there been any other discussion. I think it is time to close this support request.

The Drupal Core issue queue is not the ideal place for support requests. The 'support request' option is there for filing support issues for contributed modules and themes. There are several support options listed on our support page → (Community > Support at the top of Drupal.org) and there is Drupal Slack → . You may get better replies in one of those places.

Thanks
