STS Extensions tab stopped functioning

[bgardner]

After I installed Groovy and Grails support and restarted STS 2.3.0 the Extensions tab on the Dashboard no longer works. It looks like the image in the attachment to this post. Basically, the message "Sorry, there are no available connectors, please try again later" is all there is. And later never comes.

Any thoughts?

Brian, are you behind a proxy?

[bgardner]

Yes, but I was behind a proxy before, when I installed the Groovy and Grails support, and the Extensions window worked fine. No other changes have occurred to the proxy settings. It disappeared after I restarted, meaning that something changed in the install. I can connect to update sites fine.

Brian,

can you check your error log to see if there is something interesting when you open the Extension Tab?

Thanks for chiming in, Christian. I have an error from the CST viewer. It sounds like this:

Could this be the culprit?

Hi Brian,

honestly I don't know if this can be the root cause. Could you close the CST viewer and retry?

Christian

[bgardner]

Christian,

Now we're getting somewhere. I closed the CTS window (I really didn't know what it does anyway), opened the Dashboard, hit the Extensions tab and got the following:

Updates work, so my Internet and proxy settings are fine, as far as I can tell.

Did you ever find the cause of this?

Yesterday installed STS 2.3.0 for the first time, and get exactly the same message (Sorry, there are no available connectors. Please try again later). Likewise am also behind a proxy, however my eclipse proxy settings are correct (can connect to internet using eclipse, updates work etc). I have tried all the different Network Connections settings (Manual, direct etc.) combinations and even tried setting the proxy as a System property (in STS.ini) but still no joy.

[steveyLb]

Solved by setting all the parameters as described below (sts.ini)

Additionally.. More info/tips on this here.

steveyLb,

thanks for sharing your solution. That is very helpful for others that might run into this issue.
