I receive this error: Extension download error The CiviCRM public extensions directory at https://civicrm.org/extdir/ver=4.7.9|cms=Drupal could not be contacted - please check your webserver can make external HTTP requests or contact CiviCRM team on CiviCRM forum. However, from the browser I can go to that page and see a listing of extension.xml files. I'm trying to get the twilio sms extension installed. Drupal 7.5 CiviCRM 4.7.9
In this situation, some possibilities to evaluate:
- There is a problem on
civicrm.org, but it only occurs on a subpage. For example, in v4.7.x (and maybe 4.6.x), it fetches the subpage
- There was a problem on
civicrm.organd the failure got somehow cached. You could wait a while and try again -- or clear the caches. (Maybe use the "Support => Developer => API Explorer" to run
- Something in the web server environment is preventing it from making the request, e.g.
- A security system (such as a firewall, suhosin, or php ini setting) interferes with outgoing requests.
- The curl/http layer has a broken HTTP/SSL configuration.
In this particular case, I believe there was a change on
civicrm.org which prevented it from correctly reading several of the XML files needed for
/single, but that issue is now resolved.
