ODBC not working on some reports

[#1]

Hey there im using a ODBC connection to query our ERP Oracle.

Until Yesterday everything was fine then 2 reports started giving away connection errors.

See the attached images for the different errors i collected and the log file that the report gives after failing the reload.

Note: all the reports are connecting to the same database and i didnt had a single problem with them only 2 of them are giving problems.

Best Regards

Juan Pedro
