MarketplaceDiscoveryStrategy failed with an error Cannot complete request to https://marketplace

Question

I have installed Eclipse Version: Neon (4.6)Build id: I20160606-1100 When I launch eclipse and try to go to Marketplace via Help -> Eclipse Marketplace, I am getting the following error and hence unable to connect to marketplace server to download any plugins.

Here is the error.

MarketplaceDiscoveryStrategy failed with an error Cannot complete request to https://marketplace.eclipse.org/api/p?client=org.eclipse.epp.mpc.core&client.version=1.5.4.v20170222-1921&os=win32&ws=win32&nl=en_US&java.version=1.8.0_181&product=org.eclipse.sdk.ide&product.version=4.6.0.I20160606-1100&runtime.version=3.12.0.v20160606-1342&platform.version=4.6.0.v20160606-1100: Unable to read repository at https://marketplace.eclipse.org/api/p?client=org.eclipse.epp.mpc.core&client.version=1.5.4.v20170222-1921&os=win32&ws=win32&nl=en_US&java.version=1.8.0_181&product=org.eclipse.sdk.ide&product.version=4.6.0.I20160606-1100&runtime.version=3.12.0.v20160606-1342&platform.version=4.6.0.v20160606-1100.

Can some help to resolve this issue.

Eclipse Neon is more than 12 releases behind and more than 4 years old. Please upgrade. — howlger, Jan 19 '21 at 11:32
I am using Neon because I need to connect to "Team Explorer Everywhere" to connect Eclipse to Azure DevOps Services or Team Foundation Server. Team Explorer Everywhere plug-in works with Eclipse versions 4.2 (Juno) - 4.6 (Neon). — Santhosh M S, Jan 19 '21 at 11:56
Note that the MSFT person who answered the above advised forking and building if you want to use the Team Explorer Everywhere plugin with a more recent version of Eclipse. — Stephen C, Jan 19 '21 at 14:33

It is hard to know why that is happening. I can think of a couple of possible reasons:

It could have been a transient problem with the Marketplace server / service. I was able to load the URL in your question (in a web browser), so if that was the problem, it appears to have been resolved.
It could be a firewall and/or proxy configuration problem at your end:
- Can you load the URL in a web browser?
- Can you curl or wget it?
- Have you configured the network proxy settings in Eclipse. See How do I have to configure the proxy settings so Eclipse can download new plugins?

Thanks Stephen for your reply. I am able to access the url from my browser. And curl is giving me the following response. – Santhosh M S Jan 19 '21 at 16:23

That's OK. Eclipse should be able to cope with a redirect. Now check the Eclipse network proxy settings. – Stephen C Jan 20 '21 at 01:30
There was no proxy defined in eclipse settings. I added one with port number as 8080. Still the issue persists. – Santhosh M S Jan 21 '21 at 02:51
Why are you using port 8080? Does your proxy server use port 8080? You should use the same port as your proxy server uses. – Stephen C Jan 21 '21 at 03:07
