HTTP challenges retry

Hi @falcantaras

if you have that error, first read

Looks like you have a blocking firewall, may be a regional blocking.

  1. You can create a new order. But there are some limits.
  2. No.

It's a problem of your system. May be name servers are too slow, buggy, may be your server is too slow. If it isn't a firewall problem.

If you have such an instable system, you shouldn't try to create certificates with 50 domain names.
