Can't download symbols

Hello All,

I created a new project yesterday and it ran ok, showed the Message"App published: Hello world". Then I deleted the project folder on my computer.

I try to create new project again today and when I click to download symbols, I get error  “

Error: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. (api.businesscentral.dynamics.com:443)
A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

Do you know how can I fix it? Thank you very much.

I don't know why I create the two projects in same ways but the results are different. Below are some images about my second project:

1)launch.json

    Maybe you should try to add the tenant entity in your launch json config

    "tenant" ='YourTenantID'

    And the tenantid is found in the admincenter of your BC online. - the long number in the middle of the url

    No,it doesn‘t work. 

    I get tenant in "Help and Support" and add it in launch.json, but the error is same.

    Hi, I ran into the same problem at around 4 pm in Japan yesterday, but when I tried it today, it was already normal to download and publish. I suspect it is a problem with Microsoft, so you can try it after a while.
