Hi,
I know that there is a lot of topics about that problem and I read a lot of them for 2 days but even after delete everything and start from scratch following the guide I can't link my skill...
On my server (my own) I can see the auth request with state, scope... and after the user logged in I redirect to the redirect_uri from the request with state and code as follow:
https://pitangui.amazon.com/api/skill/link/M22LUJHGD3FQMT?state=A2SAAEAEEtZ8Udxn1EQbboOdRqk72AB4P-tywkUFVvXaT05TqGEJOz5olftwR6EUwszRtNE5RhvCSNSylYOhvfxAUsxyNVTPFqUk_zL5sSz7HaWbno0RSAi1BoQzOEMBCEXk_8E1fLZ4BWv8-0neGc799T7gUH3hev-S-JntPO5GUpRnfmWZdOgjBi2esBxZgcv85Ecdd_Z82LxIAaU5tFBeHDpHoPSzVqKgdqNP8mmSnHJ8KXSi6sI2maF_oaauPj_SsqKjjdQLePCnEiZxM-Q7gs5Kq0BB4JZ2Z-LgsWqMAcJ9AgQ-ke8eInxK8ZY0eso4zqrOVcGItJJ8_02vSWHRbFCE5Qa1R29DLWjID_g-tFsfM7aa9jE8OurIJ7tfUZpUYQch_Jwehs_GqCK07vGfHQBn5Sr3v0NZu53uwavuprzHAR0-lzbkcOOzj7-B5qS0vANpDfOcsQPNBaj5AmSP-ATHu3HbeJm2Gform69_zDDucNTBA32XVdIjEx0DXdIR6Ez_dv1dsy1ZX8f02fTo-A1ciC9HNyQ4oKeXFl-yJVBvshDIQGsmV3ZInvstB8wCDJfyb6vchjyRwnm67KQNi9Kc_Ig_0VM-Jv76_uPZK8V9UVNhaT-EICqMwIfvlhQ_bhHZGjEZ3DjtoHnK1aYgUMnaWiKHg&code=1601297597139.RC1URUNIIGVsZWN0cm9uaXF1ZQ.1601297665015
State is the one in the request from Alexa, code is a unique create from my side.
Alexa app show a waiting animation with some points then
'Unable to link .. with Alexa' 'We are experiencing a problem connecting with the skill to link your account'
For the moment the Lambda service is copy / paste from the guide and I put my skill as a trigger.
I didn't receive any token request on the server but I tested it before and it works fine.
I try from Alexa app on iPad and Android 9 and 10.
I have no log on Alexa side and no error message other than that. I don't know what to try next...
Thank.
