Last April, I asked for a HTTPS certificate "Let's Encrypt" for my application.
I installed a script to renew it autommatically.
Since April, I had no problem until last week and my HTTPS certificate has been renewed successfully.
Problem: My application is still reachable by my IP Adress but the redirection of my domain name to my IP Adress doesn't work anymore. I have no clue why.
When I check on: https://www.ssllabs.com/ssltest/index.html with my domain name, I have this error:
Assessment failed: Unable to connect to the server (but the result still return my IP Adress).
When I check on: https://crt.sh/, I have my certificate who is valid unitl 26th of November:
Not Before: Aug 28 23:00:25 2020 GMT
Not After : Nov 26 23:00:25 2020 GMT
Any clue where the problem can be ? What can I check to locate the problem ?
The problem is problably due to:
My certificate renewal ?
My redirection domaine name --> IP Adress ?
My server web ?
