It's not a bug. The concept of a 63-character hostname limit is part of: RFC1123 2.1 <https://tools.ietf.org/html/rfc1123#page-13>: Host software MUST handle host names of up to 63 characters and SHOULD > handle host names of up to 255 characters. NOTE: this includes the domain portion of the hostname to go beyond the 63 character limit in DNS up to 255 characters. It provides for up to 4 levels of 63-character names plus the '.' separator to get to 255 characters. and RFC2181 11 <https://tools.ietf.org/html/rfc2181#page-13>: The DNS itself places only one restriction on the particular labels that > can be used to identify resource records. That one restriction relates > to the length of the label and the full name. The length of any one > label is limited to between 1 and 63 octets. A full domain name is > limited to 255 octets (including the separators). Again, the same rationale is used: up to 4 levels of 63-octets plus the '.' separator character for a limit of 255 octets. One character equal one octet in latin character sets, but one character may equal two octets in multibyte character sets, reducing the effective supported length to 31 multibyte characters per label with a full domain limit of 127 characters (including the separators). In these instances, the long AWS hostnames combined with the proxy hostname suffix is pushing the length of the individual label beyond what the wire format of DNS permits, which is why the DNS lookups fail.
