Hi there
In the last 1-2 days something changed and it appears that user login requests to the API are being intercepted by Cloudflare, which effectively breaks the API
You can test with this curl request (replace [username], [password], [app]...)
curl -L --verbose --data '<?xml version="1.0"?><methodCall><methodName>LogIn</methodName><params><param><value><string>[username]</string></value></param><param><value><string>[password]</string></value></param><param><value><string>en</string></value></param><param><value><string>[app]</string></value></param></params></methodCall>' 'http://api.opensubtitles.org/xml-rpc'
the response is basically this:
HTTP/1.1 503 Service Temporarily Unavailable
Server: cloudflare
Can you look into it?
