WhatsApp Business API: "There was an error verifying this phone number"

I'm working on WhatsApp API Business. So... I did registered the docker container some times before, but I had to reinstall them and this time I was unable to register the container again. When I try to request a register code I receive this kind os response:

POST {{URL}}/v1/account {     "meta": {         "api_status": "stable",         "version": "2.19.4"     },     "errors": [         {             "code": 1005,             "title": "Access denied",             "details": "There was an error verifying this phone number. Please try again later."         }     ] } 

I checked if the docker containers are running and everything looks like working well.

[root@xxxx 2-19-4]# docker ps -a CONTAINER ID        IMAGE                                 COMMAND                  CREATED             STATUS              PORTS                                NAMES bee4beefa6e7        docker.whatsapp.biz/web:v2.19.4       "/opt/whatsapp/bin/w…"   About an hour ago   Up About an hour    0.0.0.0:9090->443/tcp                2-19-4_waweb_1 a52b9c98e2f2        docker.whatsapp.biz/coreapp:v2.19.4   "/opt/whatsapp/bin/w…"   About an hour ago   Up 23 minutes       6250-6253/tcp                        2-19-4_wacore_1 13a961e53501        mysql:5.7.22                          "docker-entrypoint.s…"   About an hour ago   Up About an hour    33060/tcp, 0.0.0.0:33060->3306/tcp   2-19-4_db_1 

Anyone that passed and fixed this before could help me?

Thanks
