HTTPS error after following troubleshooting steps

[queshaw]

I am unable to manage or add addons, because of an error connecting via https. I am using oxygen 26.1 bundled with jre under windows.

I exported the certificate and added it to the trust store used by the jre that is used by oxygen, as described in help.

Modifying oxygen.bat to include -Djavax.net.debug=ssl results in no messages being printed, but the connection still fails saying it can't connect via https. Do you have any ideas?

Also, is there a way to manually resolve the <xt:location/> paths that don't start with http?

Using fiddler as a proxy works, as a hack.

Hi,
In such cases it helps if you post the entire error message you receive.
I assume you are attempting to install add-ons from Oxygen's specific add-on update site, and not third party addons.
What we experienced in the past is that sometimes people have some kind of HTTPS proxy/firewall in their company which intercepts all HTTPS requests and changes the valid HTTPS certificate from the server side to a local signed HTTPS certificate that Oxygen ends up not trusting as valid.
In the Oxygen Preferences->"Network Connection Settings / HTTP(S)/WebDAV" page you have a checkbox named "Automatically accept a security certificate even if invalid" checkbox. You can enable it, install the add-on and then disabled it again.

Or as an alternative, if you look in our user's guide for that specific add-on's userguide page:
https://www.oxygenxml.com/doc/versions/ ... qc_23y_kpb
there is a manual installation note like:

If you have issues connecting to the default update site, you can download the add-on package, unzip it, then use the Browse for local files action in the Install new add-ons dialog box to locate the downloaded addon.xml file.
