 The default behavior for the proxy when port 80 and 443 are exposed is as follows:
 
-* If a container has a usable cert, port 80 will redirect to 443 for that container so that HTTPS is always preferred when available.
-* If the container does not have a usable cert, a 503 will be returned.
-
-Note that in the latter case, a browser may get an connection error as no certificate is available to establish a connection. A self-signed or generic cert named `default.crt` and `default.key` will allow a client browser to make a SSL connection (likely w/ a warning) and subsequently receive a 500.
+* If a virtual host has a usable cert, port 80 will redirect to 443 for that virtual host so that HTTPS is always preferred when available.
+* If the virtual host does not have a usable cert, but `default.crt` and `default.key` exist, those will be used as the virtual host's certificate and the client browser will receive a 500 error.
+* If the virtual host does not have a usable cert, and `default.crt` and `default.key` do not exist, TLS negotiation will fail (see [Missing Certificate](#missing-certificate) below).
 
 To serve traffic in both SSL and non-SSL modes without redirecting to SSL, you can include the environment variable `HTTPS_METHOD=noredirect` (the default is `HTTPS_METHOD=redirect`). You can also disable the non-SSL site entirely with `HTTPS_METHOD=nohttp`, or disable the HTTPS site with `HTTPS_METHOD=nohttps`. `HTTPS_METHOD` can be specified on each container for which you want to override the default behavior or on the proxy container to set it globally. If `HTTPS_METHOD=noredirect` is used, Strict Transport Security (HSTS) is disabled to prevent HTTPS users from being redirected by the client. If you cannot get to the HTTP site after changing this setting, your browser has probably cached the HSTS policy and is automatically redirecting you back to HTTPS. You will need to clear your browser's HSTS cache or use an incognito window / different browser.

 *WARNING*: HSTS will force your users to visit the HTTPS version of your site for the `max-age` time - even if they type in `http://` manually.  The only way to get to an HTTP site after receiving an HSTS response is to clear your browser's HSTS cache.
 
+#### Missing Certificate
+
+If HTTPS is enabled for a virtual host but its certificate is missing, nginx-proxy will configure nginx to use the default certificate (`default.crt` with `default.key`) and return a 500 error.
+
+If the default certificate is also missing, nginx-proxy will configure nginx to accept HTTPS connections but fail the TLS negotiation.  Client browsers will render a TLS error page.  As of March 2023, web browsers display the following error messages:
+
+  * Chrome:
+
+    > This site can't provide a secure connection
+    >
+    > example.test sent an invalid response.
+    >
+    > Try running Connectivity Diagnostics.

 ### Basic Authentication Support
 
 In order to be able to secure your virtual host, you have to create a file named as its equivalent VIRTUAL_HOST variable on directory
