Spaces aren't valid in urls.
Many browsers will let you type spaces, and will silently encode them for you before making the request (that is, replace them with either a plus character (`+`) or a code-point escape sequence (`%20`)).
You likely can simply replace the spaces in the URL with plus signs.

**i tried changing the certificate directory to something simpler like c:\cert\* , and also tried to open the cmd as administrator in case this was a permission issue.**
**nothing worked,**
what can be the problem ?
**also, is there a way to ignore the certificate, just as i can do on a browser ?**

The error appears to be more of a "cannot build certificate chain from the remote server back to any of the CA's you've provided" than a "cannot load the provided CA".
Let's simplify by cutting Logstash out of the mix; do you have the command line utilty `curl` installed? If so, the following should validate that the given PEM is an appropriate CA for the certificate:
```auto
curl --cacert $PATH_TO_CERT --request GET https://solarwinds-orion:17778/
```

There is presently no option in the http poller to ignore the certificate; apparently one existed in the past, but it never worked correctly and was deprecated.
We've seen some issues in other plugins where the presence of a Windows drive letter prevented things from working correctly (after all, when one works exclusively on Linux and POSIX-compliant systems, it's easy to incorrectly assume that absolute paths always start with a forward slash); I would attempt removing it (and if that works, report it as a bug on the plugin).

hi,
i tried installing logstash on ubuntu,
when i try the openssl and curl commands i get the same error...
look at this screenshot, does this give you any clues?
thanks again for your help, i really appreciate it.

The curl command looks like a success -- the TLS connection is being made successfully, and the result is a 404 (which is okay here, since we were attempting to validate the connection itself)

Try a config like this without setting the method and headers (this works is a config I'm using for a website).
```auto
input {
http_poller {
urls => {
url => "myip"
}
cacert => "cert.pem"
truststore => "truststore.jks"
user => "admin"
password => "pass"

}

i can see that there is no path specified for the .pem and .jks files, is that how you use it too ? if so , where do you actually put the files, so that they will be found ?
thanks,
David.

I edited out the path but you need to set something like /path/cert.pem and /path/truststore.jks. Though if you put them in the logstash root directory you might not need to set a path. Didn't test that so just set a path.
