Best regards,

Hi Simon, I cannot be sure what the problem was but I have seen similar issues when the server did not have access to cryptographic routines needed to generate the login challenge. Best regards, Panos.

Hello all

I had an old monetdb installation on my Windows laptop -Did the upgrade in Oct2020-SP5 Bugfix Release (11.39.17)

It really looks like I can start the server

C:\Program Files\MonetDB\MonetDB5\bin>mserver5

# MonetDB 5 server v11.39.17 (Oct2020-SP5)

# Serving database 'demo', using 4 threads

But when I want to use the mclient, it asks the user and password and then... nothing and after a few minutes I have this message

Challenge string is not valid, it is empty

Same thing with an ODBC connection : after a long time, it fails.

I have reinstalled Monetdb but nothing changed.

I have no idea of what's wrong.

Best regards,

Simon
