 I allways get the message "Download failed. A valid URL was not provided"
 when I try to reinstall wordpress, update translations, plugins or install
 news plugins. I can do it manually.
 Searched these text message in code files at github, then added a number
 for each for differentiate and find the message becomes from wp-includes
 /class-http.php at line 264.
 I put these code into the "if" condition

 file_put_contents('path(to/the/file/variable.txt',$url,FILE_APPEND);
 file_put_contents('path(to/the/file/variable.txt',$arrURL,FILE_APPEND);

 and allways the variables are empty...but if I put the catch code before
 the if condition get these values

 As you can see some url´s have loss the ":\/\/" between the http(s) and
 the url, I don´t know if this is the expected behaviour, but why the
 varibles are lossing their values between lines 262 and 264?

 I have tried to update/install flushing all caches, disabling all
 plugings, disabling child theme..... and allways get the same message
 "Upgrading from..URL Donwload failed. A valid URL was not provided"

 P.S. Sorry for my bad english.
