Power BI Service refresh issue due to credential authentication failure

[jlpnea]

Hi every one,

my scheduled and manual refresh doesnt  work anymore

i have a on-premise datagateway (personnal mode) and the source is a simple excel file on my PC

the pb comes from the failure of source credential (excel file on my pc)

i am one organisation azure active directory. i put windows

my gateway is ok (green)

the erreor message is this one (translate from french) 

Failed to update data source credentials: The input is not a valid Base 64 string because it contains a non-Base 64 character, more than two padding characters, or a non-base character conforms among filler characters

any one can help me ?

Hi @jlpnea ,

It refers to an error during decoding.It may related to gateway version.

Please upgrage your gateway to the latest version (both personal and enterprise) and have a try again.
