after receiving this error - the signature of the blocks doesn't happen further

The error has been received 4 times already (find in the chat):

• fall 2018
• 18.09.2019 and 19.09.2019
• 31.01.2020 - (again 2 nodes broken for signing )

We are working on #276 at this point and will start investigating this one as soon as its addressed.
