Invalid Response and Acme Script Encountered some errors

Hi I am trying to install the SSL for my domain https://www.androidflashtools.com/, I moved to another server from previous server and each time I click the Let’s Encrypt button and the Log says this.

androidflashtools.com:Verify error:Invalid response from http://androidflashtools.com/.well-known/acme-challenge/vX5YCAvOwuXzTmNjlGWOqZHbokowTqKOrHmwR16EIdc:
****************** Acme script finished execution ******************
Acme script encountered some errors

It says Acme script encountered some errors and invalid response. If in this case how to solve the existing problems?

How are you attempting to generate this? Please fill in as many of the following questions as possible, so that we may assist you, noting that “ran this command” could be a description of some GUI interface you used instead of a command line entry, if more relevant:

My domain is: www.androidflashtools.com

I ran this command: ???

It produced this output:
androidflashtools.com:Verify error:Invalid response from http://androidflashtools.com/.well-known/acme-challenge/vX5YCAvOwuXzTmNjlGWOqZHbokowTqKOrHmwR16EIdc:2 Acme script encountered some errors

My web server is (include version): ???

The operating system my web server runs on is (include version): ???

My hosting provider, if applicable, is: ???

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

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

Sorry for the incomplete information

I am using Linux OS VPS OpenVZ, and WebuZo as control panel. And host server OpenVZ1004. And my hosting provider is Interserver.net.

Thanks! So, I don’t see much info about this host’s support for Let’s Encrypt. Are you running this from the command-line, or from a control panel? I don’t see them on the big list of hosting providers that integrate with LE, but that doesn’t mean they don’t integrate.

I did take a poke at your domain, and noticed a couple things. First, requests to .well-known/acme-challenge are being redirected back to the base domain (e.g. http://www.androidflashtools.com/.well-known/acme-challenge/test (a non-existant file) just gets a redirect to http://www.androidflashtools.com. I’d expect a 404.) Since it’s possible that the non-existent file is causing that redirect, could you try putting a test text file in that location and see if you’re able to load it in a browser? The way Let’s Encrypt validates over this challenge type is to put a challenge file there and retrieve it. If it comes back mangled, or you serve some other page, it will fail. That’s what’s happening here.

One other thing - it looks like you’re using Cloudflare and already have Cloudflare SSL set up for this site. Did you know this already?
