Answer 1

I think the answer is found in the log:

You probably access the destination server through a proxy server that is not well configured.

If you can use another proxy server you can set it in the sbt start script:

-Dhttp.proxyHost=<proxy> -Dhttp.proxyPort=<port>

Answer 2

For me, this problem was caused by a temporary issue with our company's DNS server. I mention this only because this question is one of the top results when searching online for the above error message.

Answer 3

In WINDOWS environment, simply add following line in the sbt/conf/sbtconfig.txt

-Dhttp.proxyHost=PROXYHOST 
-Dhttp.proxyPort=PROXYPORT 
-Dhttp.proxyUser=USERNAME 
-Dhttp.proxyPassword=XXXX

or the Https equivalent

-Dhttps.proxyHost=PROXYHOST 
-Dhttps.proxyPort=PROXYPORT 
-Dhttps.proxyUser=USERNAME 
-Dhttps.proxyPassword=XXXX

or simply set following variable on dos command prompt

set JAVA_OPTS=-Dhttp.proxyHost=XXXXXXX -Dhttp.proxyPort=YYYY -Dhttp.proxySet=true -Dhttps.proxyHost=XXXXXXX -Dhttps.proxyPort=YYYY -Dhttps.proxySet=true
