Error SignatureNotMatchCredentialError when refreshing data

[Cado_one]

Hi,

I use an on-premises data gateway (personal mode) to refresh data stored in Excel files on the server of my company. It worked perfectly for the last 2 months and suddenly it stopped last tuesday for no obvious reason.

It gives me this error :

Datasource error :	{"error":{"code":"DM_GWPipeline_Gateway_SignatureNotMatchCredentialError","pbi.error":{"code":"DM_GWPipeline_Gateway_SignatureNotMatchCredentialError","parameters":{},"details":[],"exceptionCulprit":1}}} Table: TBL_LOCATION.
URI du cluster:	WABI-WEST-EUROPE-redirect.analysis.windows.net
ID d'activité:	3634d8a6-8094-43cd-b76e-8ecee4fd5bbf
ID de demande:	83a4a888-fe40-9971-491b-8e6acdb56a8e
Heure:	2020-08-18 07:07:32Z

And when I try to edit credentials I got this :

In english, it says that the update of credentials failed because the specified account doesn't exist.

To fix this I tried to update the gateway, and also uninstall to install again the gateaway but it didn't change anything.

Any idea to help me cope with this error will be appreciated.

Thanks in advance,

Cado

Hi @v-diye-msft 

Thank you very much for your answer.

After investigation, the password of the domain owner was effectively changed.

Have a nice day.
