We are unable to login linnwork via Linnworks desktop. the system said "unable to establish a connection with the database. Please check your connection and firewall settings elase contact Linnworks Support."

I am sure my internet connection is good and no firewall issue. Because I am using the linnworks desktop many many year with same internet setting without any change.

Please help to check.

The problem fixed. Finally we need to reinstall the desktop linnworks on all PCs

We are having the same problem.
