Citation relations can't retrieve data

[Miso-1]

Hi,
I have a problem with the citation relations tab. It only displays "No articles found"

JabRef 5.15--2024-07-10--1eb3493
Windows 10 10.0 amd64
Java 21.0.2

Steps to reproduce:

1. Open the citation relations tab in entry editor

Details:
I am using Jabref from within a company network. I had a similar error log when I tried to import data using the DOI number. This problem could be resolved by deactivatin SSL decryption for https://www.doi.org/ and https://www.crossref.org/
Now the same issue seems to occur for the citation relations. Already deactivated SSL decryption for https://opencitations.net/ but the problem persists. I am able to use the same library on another device in another network (private network) without any problems. -> The problem is either machine or network related.
Could someone give me a hint which setting could be the issue?
Or are there any other domains which need to be considered for fetching?

Thanks for your help.

Hi, you can try to add your company SSL cert to the JabRef preferences under Network -> SSL

Hi,
unfortunately this doesn't work. I also tried to configure proxy settings but I only get the message "Connection failed" without any additional information (no messages in the event log)
