Welcome to the CodeIgniter forums!

Are you on a network administered by a third party (i.e at work or college)? If so, that port may be blocked, and you may have to install it manually.

Are you able to install any other sparks? I would suggest backing up your current project and giving it a go.

Yeah actually i've been administrated by my work, maybe can be that. I could install another sparks only the oauth sparks are the only one that i can't. When i install the sparks in manual way i got an error that said that i don't have a spark in the spark path sparks/oauth2/0.4.0, any idea about that?

None whatsoever. Sorry.

How did you install it manually? You should just need to grab the files and put them into the relevant directories, which shouldn't cause any kind of spark error, since Spark is a command line PHP application, and to my knowledge, can't be run through your Web browser.
