When I tried to use Galaxy 2.2 I received the following message around 2 pm on October 15, 2006:
Proxy Error
The proxy server received an invaild response from an upstream server.
The proxy server could not handle the request GET/.
Reason: Error reading from remote server.
I am using Verizon DSL to access via Microsoft Explorer.  I have tried to access Galaxy since 10 pm last night without success or this error message until now.  The page would just refresh and say done at the bottom.
Hope this helps.
