Hi,
It seems that this error can also occur on some proxies that don't support "100 continue" expectation. The workaround is to add the following to the dexplore.exe.config file.
<configuration>
<system.net>
<settings>
<servicePointManager expect100Continue="false" />
</settings>
</system.net>
</configuration>
