Greetings,
It appears that your hosted DevPortal trial expired on December 23rd. You first posted this issue on the 13th, though. So, unfortunately, your trial expired before we could get back to you.
My *guess* is that it was port blocking. The hosted servers are fairly locked down. The guides on the DevPortal are careful to give instructions that we know will work. It appears that you were trying to do something with Eclipse other than something that we'd instruct in a guide. Because of our security, that may not be viable. But, still, sorry for the delay in response.
I may have a solution, however. Our downloadable trials run for 120-days, and you run them on your own system. As such, they're not locked down like the hosted servers are.
You may download them here: https://developer.thingworx.com/en/resources/downloads
If I'm in error and you were trying to follow the instructions in one of our guides (such as the Eclipse "Create an Extension" guide here: https://developer.thingworx.com/en/resources/guides/eclipse-plugin-thingworx-extension-development-tutorial), please let us know so that we can correct our instructions.
Thank you,
Jason
