Title: Lets Encrypt Challenge was invalid error
Post by: hectorp on July 10, 2024, 10:16:45 AM

Hi

While trying to run my first SSL NTWS app with Lets Encrypt certificate.

But it is giving this error message while trying to get the certificate.

Appreciate any help on this.

Hi,
As I can see your port 80 is closed

Hi,
I went through this about a year ago.  I found that many ISPs block port 80 so that their customers won't use port 80 to run web sites from their home. They reserve use of port 80 for more costly business accounts.  There is a DNS  challenge that Net Talk has documented to get around this problem.  That is worth looking at.
