December 2021 Office Relase Broke DB2 Connection to AS400

[mstgermain]

Good Morning, 

We are having a isuse that since the December O365 patching are users that try to make a connection using MS DB2 is getting the following error. 

[DataSource.Error] Microsoft Db2 Client: An internal network library error has occurred. A network level syntax error has occurred. SQLSTATE=HY000 SQLCODE=-379

It seems that this happen before a few times and the fix for some where to change the creditinals but does not work for us. We can roll back office and everthing works again but that causes other issues for the user. 

Solved: April release broke certain DB2 connections: SQLST... - Microsoft Power BI Community

Anyone else having this issue ? 

Apperciate the help in advance

Hi

Same problem here. My Power Query (Excel and PowerBI) connection to a AS400 DB2 Database worked for more than 1 year. A few weeks ago it just stopped working.

Error message I get is the same as mentioned above.
