Refresh token is not working properly

[patriarcholeksiy]

When I receive the token using the authorization code, the response indicates that the upgrade token is available for renewal within 8 hours, but when I try to use it, an error appears: 400 Invalid request: "{"Error code":"errors.com.epicgames.account.auth_token.invalid_refresh_token","ErrorMessage":"Sorry update token "XXXXXXXXXXXXXXX" is invalid","messageVars":["XXXXXXXXXXXXX"],"numericErrorCode":18036,"originatingService":"com.epicgames.account.public","intent":"prod","error_description":"Sorry, the update token "XXXXXXXXXXXXXXX" is invalid","error":"invalid_grant"}"

If I use refresh_token for 30 minutes, then it works fine. Can you tell me what to do? Thank you in advance!

refresh tokens work properly, its just that when you launch fortnite all auth sessions will be killed (so also refresh tokens)

Is there a way around this?

Thats how authentication works, no.
