Since last Friday I can no longer access the Toolforge database using my username and password (which worked before). I get a message saying "User access denied using password:YES". I tested the access from DataGrip and from my Python code and in both cases I get access denied.
I have seen a related task https://phabricator.wikimedia.org/T183644 and followed the instructions at https://wikitech.wikimedia.org/wiki/Portal:Toolforge/Admin#Debugging_bad_mysql_credentials but when I test that I get a message saying "ERROR 2003 (HY000): Can't connect to MySQL server on 'm5-master.eqiad.wmnet' (110 "Connection timed out")".
What can I do to fix this and have access to the DB again? Thanks a lot in advance.
