I have Jenkins where all jobs fail in Sonar Quality Gate for the same reason:

[Bitbucket] Build result notified
hudson.remoting.ProxyException: net.sf.json.JSONException: Invalid JSON
String
and few lines after it, the next info:

Caused: hudson.remoting.ProxyException: java.lang.IllegalStateException: Unable to parse response from
http://*****.com:XXXX//api/ce/task?id=AWvbAMmYTj8ZIUmGCNc1

I can't understand why I'm getting two backslashes instead of one after the port. I couldn't figure out where it's coming.
