Refreshing token returns error 400 (iPlanet session has been expired.)

After getting authentication token, we refresh it every 4/5 of the expire time (approx. 4 min).
From time to time (sometimes several times a day, sometimes once every few days), such refresh_token requests fail with 400 error and message "iPlanet session has been expired."

What can cause such error? How to prevent it?

Hi @Serge,

Are you experiencing the token expires approximately every 18 hours? This may be the reason why it is happening. I believe there is a setting within your specific account that may have set this up - I believe it is the default. In addition to what you are doing, i.e. refreshing every 4/5 of the expire time, you can also refresh apply 4/5 of the 18 hour window. I would also reach out to your Refinitiv account manager to see if this setting can be turned off.

I too get this response. I have an application that I use to test the EDP API similar to Postman but one that I wrote myself.

I run up two instances I1 and I2.

I1 GetAccessToken (grant_type=password) returns access_token and refresh_token.

I2 GetAccessToken(grant_type=password)returns access_token and refresh_token.

I1 RefreshTokens (grant_type=refresh_token) returns 'iPlanet session has been expired'

I2 RefreshTokens (grant_type=refresh_token) returns access_token and refresh_token.

I1 RefreshTokens (grant_type=refresh_token) returns 'Refresh token does not exist.'

Same client_id for both instances.

Thank you @nick.zincone.1

This may be it. We are currently evaluating Elektron in Cloud service and have trial ID that probably has that setting you mentioned.
