My hosting provider, if applicable, is:

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

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

Hi @sofievingstedt

if you don’t have root access and if you don’t use a control panel: How do you manage your server?

PS: Checked your domain -

You have a new certificate created:

Issuer not before not after Domain names LE-Duplicate next LE
Let’s Encrypt Authority X3 2020-03-12 2020-06-10,,,,,,, - 8 entries duplicate nr. 1

And you use it:
expires in 89 days,,,,,,, - 
8 entries

Looks like you had only a temporary problem.
