Could not register datasource in gateway

Hi  Sinerka01 ,

1. Whether the gateway is updated to the latest version, if not, update it to the latest version

https://docs.microsoft.com/en-us/data-integration/gateway/service-gateway-update

2. The credentials under the gateway cluster settings are entered incorrectly (for example, the password has been updated recently or the password of the login account has been recently changed, but the gateway settings have not been updated), if the password of this account is set to expire or the password of the data source is not updated, the user may receive a connection error. So please check/update for fields - contact information and password under Gateway Cluster settings.

3. Stop the On-Premises Data Gateaway Services and restart them again.
