We have a java application that connects to ExactOnline for performing the operations. The connection works fine for almost 9days and then it will start complaining about the below exception:
"Request from start.exactonline.nl returned an error (response code: 400, response: { "error":"invalid_grant","error_description":"Token is not allowed, because of invalid or empty chainId"
After encountering this error we have to force re-authorize the application by the user to get the new accessToken.
Now I am getting the below error as well:
"Request to token endpoint https://start.exactonline.nl/api/oauth2/token" Any help would be appreciated.
The error message it's background and the solutions are explained at https://forums.invantive.com/t/exact-online-error-token-is-not-allowed-because-of-invalid-or-empty-chainid-on-exact-online/2226
