@Jesus Orlando Aguilar Contreras Thank you for reaching out to Microsoft Q&A, apologize for any inconvenience caused on this.
As per the error message "Azure.Core: No such host is known. ([MyStorage].blob.core.windows.net:443). System.Net.Http: No such host is known." it looks like you function is communicating with storage account and not able to communicate.
I have looked into the backend logs and I can see the same behavior that your function is not able to communicate with storage account I have further looked into the latest logs and I could see that your function is able to communicate with the storage account.
I believe you storage account might be in virtual network or there might be any access restriction configured and which would have caused this issue. Do let me know if you are still facing the issue.
Feel free to reach back to me if you have any further questions on this.
