Cannot contribute translation

Hello community,
I am having troubles submitting contribution to translate.erpnext.com.
When I click “Contribute” button I am getting the following dialog box:
“Something went wrong while contributing translation. Please check error log for more details” and the translation is not contributed.
Any tips what it might be or where to look on the server for clues?

Cheers,
