Lets Encrypt certificate renewal Fails (Azure webapp)

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is: https://uat.health.lynkco.biz/

I ran this command: No command, Using Lets encrypt extension on my Webapp in Azure.

It produced this output: Microsoft.Azure.WebJobs.Host.FunctionInvocationException : Microsoft.Azure.WebJobs.Host.FunctionInvocationException : Exception while executing function: Functions.RenewCertificate ---> System.ArgumentException : 'authority' Uri should have at least one segment in the path (i.e. https:////...) Parameter name: authority at Microsoft.IdentityModel.Clients.ActiveDirectory.Authenticator.DetectAuthorityType(String authority) at c:\workspace\azure-activedirectory-library-for-dotnet-v3-master-VS2017\src\ADAL.PCL\Authority\Authenticator.cs : 133 at

My web server is (include version): Azure app service with .net core 3.0

The operating system my web server runs on is (include version): Windows

My hosting provider, if applicable, is:

I can login to a root shell on my machine (yes or no, or I don't know):

I'm using a control panel to manage my site (no, or provide the name and version of the control panel):

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot):

Hi @Basav, and welcome to the LE community forum :slight_smile:

The problem seems to be within that file [at line 133?]
But this isn't likely the best place to get help with:

Whomever wrote/supports that extension would be my best guess for help.


Thank you for the response, I will check with the extension owner.

Meanwhile, the Automatic renewal documentation page is not available. is it the same for everyone?

I get a forbidden reply from an nginx server.


It's a super old article so it may not be very relevant anymore but it looks like they just dropped the .aspx from the url: Automating Azure Resource Group deployment using a Service Principal in Visual Studio Online: Build/Release Management - Azure DevOps Blog
