Below error is thrown when we try to access Marketplace. Have tried exporting the certificate from marketplace link and adding it to the JRE folder. Tried in all 3 network connections possible like Direct, Native and Manual. Also, tried adding -Djava.net.preferIPv4Stack=true in the INI file. Tried different versions of Eclipse and all are failing with the same error. Please suggest any other possible resolutions.

Your Eclipse version is 6 years old, and your Java runtime is approaching a year old. Both should be updated.

Multiple Eclipse versions have been tried and we are getting the same error even in the latest version of Eclipse. Java/Eclipse versions does not seem to be an issue here. Attaching the screenshot and error from latest Java version & 2021 Eclipse version.

The query string here suggests you are using Eclipse 4.18. In any case, this problem is caused by missing cacerts. It might be the case that you are in a corporate environment where your proxy injects certificates into the communication stream that are not know to the Java runtime you are using, like in this case:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=578341#c23

Adding the certificate to your certificate store is the only way to fix the problem

I would agree. Could you please explain a bit more around the following steps on how this should be done.

4.) Instructed Firefox to save the certificate chain as a PEM file.
5.) Created a copy of my cacerts file.
6.) Imported the chain from the PEM file into the copy.
7.) Modified my eclipse.ini to contain -Djavax.net.ssl.trustStore=<PATH_TO_COPY>
in the vmargs section.

Thanks in advance.

To answer those types of questions, I would use Goolge to search for answers. I've never had to do this myself, but I've been at companies where they did this...
