web search: researchgate error (server unavailable?)

JabRef version

5.9 (latest release)

Operating system

Windows

Details on version and operating system

Windows 10 22H2

Checked with the latest development build

• I made a backup of my libraries before testing the latest development version.
• I have tested the latest development version and the problem persists

Steps to reproduce the behaviour

1. Go to web search
2. Select researchgate
3. Enter any search term e.g. "dinosaur"
4. Following error occurs saying researchgate server is unavailable

But doing the same search on the website is just working fine...
