@ISABELA CAROLINA PADILHA Welcome to Microsoft Q&A Forum, Thank you for posting your query here!
If your issue is related to the Azure Functions runtime is unreachable
, then please follow this article.
If your issue is related to the message Portal editing is disabled
, then check in case you are on consumption or elastic-premium plan then please verify if WEBSITE_CONTENTAZUREFILECONNECTIONSTRING and WEBSITE_CONTENTSHARE setting is missing from the Configuration setting of your function app.
Please configure these two app settings according to File Shares in your Azure Storage Account.
Also check what option was used while creating the function App ? please note that not every combination (SKU, language, operating system) supports the editing of function from azure portal.
Could you please elaborate on your ask and provide more details ? This will help us to assist you better. Awaiting your reply.
