Aren't you behind a proxy?
Can you provide a reproducer?

[billsoftltd]

I don't use proxy.
I don't know how to reproduce it. Is it possible that the server was unavailable or timeout?

[kwart]

Yes, service outage or network issues could be the reasons.
DId you already succeed to proceed with the signature?
