Secure HTTPS Connection error when trying install an add-on

[antonyterrence]

In Oxygen XML Editor 24.1, when I go to Help > Install the Add-ons to Install and select https://www.oxygenxml.com/InstData/Addo ... teSite.xml to install the default add-ons, I get the following error:

Code: Select all

There was a problem establishing the secure HTTPS connection. In case the server you are trying to connect to uses self-signed certificates, read the 'Troubleshooting HTTPS' section from the user manual.
 Full error message: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

When I put the URL in a web browser, the page loads though.
I tried the instructions on the following troubleshooting page, but was not able to resolve the problem.

Hi,

I don't have problems installing add-ons from the Oxygen add-ons update repository. Is it possible you have some intermediate company specific proxy HTTP server which may have a self signed certificate that Oxygen does not accept?
In the Oxygen Preferences->"Network Connection Settings / HTTP(S)/WebDAV" page there is a checkbox named "Automatically accept a security certificate, even if invalid". Maybe you can check the setting, save the settings, install the add-on and then uncheck the setting again because it may cause a security risk.

Regards,
Radu

Thank you, Radu. That workaround did the trick.
