[Pimpodile]

JabRef version on
JabRef 5.1--2020-08-30--e023aa0
Windows 10 10.0 amd64
Java 14.0.2

Still broken in
JabRef 5.2--2020-12-24--6a2a512
Windows 10 10.0 amd64
Java 14.0.2

• Mandatory: I have tested the latest development version from http://builds.jabref.org/main and the problem persists

The internal update function is broken.

Steps to reproduce the behavior:

1. Click on "Check for updates" option
2. Error box shows up

Cannot reproduce this in the latest dev version. https://builds.jabref.org/main/

Are you behind a proxy server?

Solution options:

1. Silently trust SSL certificate for this call
2. Silently trust all SSL certificates
3. Preference for "trust all SSL certificates"
4. Offer user a button to ignore SSL check for the current call
5. Offer user to install an SSL certificate into JabRef SSL key chain

@Pimpodile We found a work around - could you please test https://builds.jabref.org/pull/7890/merge/?
