Complicated module update error HTTP error 0 I'm recently getting the error below:


  HTTP error 0 occurred when trying to fetch https://ftp.drupal.org/files/projects/captcha-7.x-1.5.tar.gz.
  Downloading updates failed:
  
  Failed to download captcha from https://ftp.drupal.org/files/projects/captcha-7.x-1.5.tar.gz

I'm running my website on a shared platform, so I can't change the parameters of PHP...

Based on this long thread drupal dot org/node/247009 I have already tried several many potential solution with no luck so far. This is what I tried and it did not work:


gave 777 recursive permissions to tmp and site/default/
tried on different browsers (Edge, Firefox, Chrome)
in jquery update module I changed the jquery default version to 1.10
I set the jquery source from google, and I set the jquery to non-minified
I checked and in settings.php I do not have any base url set
the file which failes to be downloaded is very small in size 103KB, so I
    guess it's not about uploading to large files
I checked my PHP version and it did not change recently it;s 5.3.29
I also checked the PHP memory limit and it's set to 256MB which to me it's not that low for uploading a 103KB file 
I I tried the update of a different module, and I get the same error


What could be the problem? Where to look next?
I had the exact same problem and the solution given by Neograph734  was to manually add the module. If you have Filezilla, connect to your drupal site files. Go to Sites-->all--->modules--->  Locate the captcha folder, delete everything in that folder. Upload the updated captcha module files. (Download and upzip first).

Once this is done, you will also need to update the database. It will show you where to do that once you click on reports. Once the database is updated, your module should now be upgraded and working. :)

No more nasty notices about having to upgrade it!
