I have tried this with many update sites and I got the same error, so what is this?if someone interested in the full log I can post it.

Thanks

I also had the same problem, What I did was I had previously set a proxy address so when I went to a network that required no proxy, I got that error.

I solved the problem by

Preferences
Network connection
Then set network provider to Direct.

Eclipse – How to you speed up Eclipse

The three most influential factors for Eclipse speed are:

Using the latest version of Eclipse (2020-06 as on 26 June 2020)
Note that David Balažic's comment (July 2014) contradicts that criteria which was working six years ago:

The "same" workspace in Indigo (3.7.2) SR2 loads in 4 seconds, in Kepler SR2 (4.3.2) in 7 seconds and in Luna (4.4.0) in 10 seconds. All are Java EE bundles. Newer versions have more bundled plugins, but still the trend is obvious. (by "same" workspace I mean: same (additionally installed) plugins used, same projects checked out from version control).

Launching it with the latest JDK (Java 14 at the time of writing, which does not prevent you to compile in your Eclipse project with any other JDK you want: 1.4.2, 1.5, 1.6 older...)
```
  -vm jdk1.6.0_10\jre\bin\client\jvm.dll
```
Configuring the eclipse.ini (see this question for a complete eclipse.ini)
```
  -Xms512m
  -Xmx4096m
  [...]
```

The Xmx argument is the amount of memory Eclipse will get (in simple terms). With -Xmx4g, it gets 4 GB of RAM, etc.

Note:

Referring to the jvm.dll has advantages:

Splash screen coming up sooner.
Eclipse.exe in the process list instead of java.exe.
Firewalls: Eclipse wants access to the Internet instead of Java.
Window management branding issues, especially on Windows and Mac.

Dec. 2020, Udo conforms in the comments

From version 4.8 (Photon) an up there was a steady speed gain after each version.
The main platform was optimized every release to load faster, enable more features for the dark theme and to add more features for newer Java versions for the Java development tools.
Especially with-in the last 3 versions the startup time was increased a lot. There should be a significant increase in start-up time with the newest version of Eclipse 2020-12.

In my experience it started a lot faster with each new version.
But: There are still plug-ins which do not follow the new way of using the Eclipse API and are therefore still slow to start.
Since the change to Java 11 as the minimum runtime version starting from Eclipse version 2020-09 at least the core system uses the newer features of the JVM. It is up to the providers of the other plug-ins to upgrade to newer APIs and to use the full power of modern CPUs (e.g. concurrent programming model).

Java – Eclipse/Java code completion not working

Try restoring the default options in 'Windows > Preferences > Java > Editor > Content Assist > Advanced'

An example of the kind of data you see in this preference screen, however not necessarily what you currently have.

eclipse content assist setting

(From Vadim in this blog post " Content Assist Duplicates in Eclipse (Mylyn)":
if have duplicate Mylyn entries, uncheck the duplicate entries that do not contain "(Mylyn)" in their name)

The Eclipse help page defines the default list to restore:

Select the proposal kinds contained in the 'default' content assist list:

Other Java Proposals,

SWT Template Proposals,
