I got a message from the “Let’s Encrypt Expiry Bot” that my Azure certificates will expire soon:
Your certificate (or certificates) for the names listed below will expire in 19 days (on 02 Apr 20 00:23 +0000). Please make sure to renew your certificate before then, or visitors to your website will encounter errors.
The same error in the Troubleshoot section in web app TLS/SSL settings is:
Certificate with Thumbprint
11f6a8011f534bf2e29ba459bca547442107b35a bound to the hostname
premimanager.premisol.net will expire
in 13 days .
I have been using Let’s Encrypt for my Azure Web App certificates now for over 1,5 years and so far I have never got expiration messages like these. Instead all has worked automatically fine with the 90 day certificate renewals.
I have not touched anything in my Web App TLS/SSL settings during the last year, so I am wondering what is causing this problem. The installation of Let’s encrypt in Azure was very difficult and I hope I don’t have to touch anything there…
My questions are:
- why has the automatical renewal stopped working after working fine in over a year?
- can I check it with some command i.e in the Portal or in Kudu Diagnostic console?
- is it possible to do a manual renewal from the Azure Portal? This would be fine with me.
- I still have 13 days to do something. Could it be that the renewal is delayed for some reason?
My domain name for the first app is:
I have four other web apps using Let’s encrypt in the same domain behaving exactly the same way
