Let's Encrypt Certification Failed to update

Let's Encrypt was working perfectly fine until today. When I try to get a new certificate, it gives the error below.

Getting certs from local store (Production)

• Reading certificate files
• Setting LE cert for default domain.
• Certificate has 30 day(s) left.
• Asking for new certificate because of expire time.
• Generating private key...
• Setting up ACME client...
• Creating certificate request...
• Requesting certificate from Let's Encrypt...
• Failed to obtain certificate: 111.111.111.111: Fetching http://MyWebServer.com/.well-known/acme-challenge/1234567890abcdefghijklmnopqrstuvwxyz: Timeout during connect (likely firewall problem)

I tried to turn off the firewall, no diff.
I can not find ".well-known/acme-challenge/" in the mechCentral directory.
Something has changed on Let's Encrypt refused to get a certificate.

Any solution???????????

2 lines are added to letsEncrypt from online forums but no difference..
