While trying to fetch from the collaboration server into a newly created database, I was notified of an "error during fetch." I do not have a local copy of the database saved. Any ideas about what the cause of this error could be? Is there any way around this error? 

Thank you.

There can be many reasons, from interrupted internet connection to insufficient local disc space to access issues with the repository. Typically there is more information provided?

Thank you - and the repository is ok? Because of the java.nio.BufferUnderflowException that causes this?

I was thinking it may be an issue with the repository - Federal Commons repository - which underwent some updates recently. I've never had this issue before where my database is 'stuck' on the repository and I am unable to pull it into a local database.

Which version of openLCA are you using and do you have access to the collaboration server yourself (to access the logfile, after this error occurs)? As a workaround, you can download the repository from the web interface of the collaboration server via the JSON-LD export and import into openLCA with the JSON-LD import, and afterwards connect to the repository and fetch (this should recognize, that you already have all the data in your local database, and bring you up-to-date).
