  1. I have tried multiple other instructions that did not work, however, this worked perfectly!!! THANK YOU!

  2. Thanks a lot as I have tried a lot other options but this steps mentioned is article worked perfect for me..!! Thanks a lot again.!

  3. I follow every step and still i got this error. Checked DNS, IP, everything is alright

    – The following errors were reported by the server:

    Type: connection
    Detail: Fetching
    Timeout during connect (likely firewall problem)

    To fix these errors, please make sure that your domain name was
    entered correctly and the DNS A/AAAA record(s) for that domain
    contain(s) the right IP address. Additionally, please check that
    your computer has a publicly routable IP address and that no
    firewalls are preventing the server from communicating with the
    client. If you’re using the webroot plugin, you should also verify
    that you are serving files from the webroot path you provided.

  4. You have to use DNS challenge rather than http or https validation. I had the same problem and was able to resolve by using DNS challenge.
