Can't fetch with ISBN (parsing error)

[sbarfurth]

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

JabRef version 4.3.1 on Windows 10

Steps to reproduce:

1. Add a new entry
2. Select ID type ISBN
3. Enter an ISBN (e.g. 9780262305662)
4. Click "Generate"

An internal parser error occurred
org.jabref.logic.importer.FetcherException: An internal parser error occurred
at org.jabref.logic.importer.IdBasedParserFetcher.performSearchById(IdBasedParserFetcher.java:93)
...
at java.lang.Thread.run(Unknown Source)
Caused by: com.mashape.unirest.http.exceptions.UnirestException: java.net.UnknownHostException: www.ebook.de

Note: I use a corporate Proxy. It is properly configured and searches through some of the databases from within the program work. I believe it is not related to this issue.

It looks like you are having problems with your network connection or JabRef is blocked by your firewall. The log file tells you that JabRef was not able to connect a) github (to check for updates) and b) ebook.de to get bibliographic information about the book.

Duplicate of #4198

[sbarfurth]

Considering I opened mine first it's hardly a duplicate. Thanks for the quick responses, hope #4198 gets fixed soon!

[stefan-kolb]

Yah technically it's not 😉 but the other one describes the root cause, so I closed this one sorry 😄

[sbarfurth]

Haha, I'm not mad. Doing good work here!
