Can't access Eclipse marketplace

Question

I can't seem to access the Eclipse marketplace. I'm using Juno 4.2. I tried deleting eclipse and removing all plugins, deleting my .metadata, and deleting the eclipse app data.

I've tried switching my default browser from firefox to chrome, I've tried turning on and completely off Windows firewall. I'm at home.

I was able to get eclipse updates, though. When I try to report a bug for the marketplace I get a different error.

When I try to connect, I receive quite a few errors.

First one is a warning:

Connection to http://marketplace.eclipse.org/catalogs/api/p failed on Connection reset. Retry attempt 0 started 

Second is an error:

Cannot install remote marketplace locations.:  

Third is another error:

Unexpected exception 

Here are the stack traces in order received:

Answer 1

Here's the solution,

If you are a constant proxy changer like me for various reasons (university, home , workplace and so on..) you are mostly likely to get this error due to improper configuration of connection settings in the eclipse IDE. all you have to do it play around with the current settings and get it to working state. Here's how,,

1. GO TO

Window-> Preferences -> General -> Network Connection.

2. Change the Settings

Active Provider-> Manual-> and check---> HTTP, HTTPS and SOCKS

If your active provider is already set to Manual, try restoring the default (native)

---

That's all, restart Eclipse and you are good to go!
