Thanks @gls
I had the OAuth method since July 2021 … but… since Exact requires exact continuity between refresh tokens as described here Exact Online error message: Old refresh token used I am using OAuth accross multiple iIvantive product (QueryTool and Data Hub for me) AND also multiple Exact databases (=multiple EOL divisions)
I moved to TOTP because of the above described error.
Am I wrong ?
I am using Beta 20.1.537.
