1.x branch Hostnames longer than 26 characters fail as invalid

[swirtSJW]

IN 1.x branch the check for Valid URI is incorrectly calling any URI with a host name greater than 26 characters invalid.

It comes down to this REGEX pattern.

We are getting failures for hostnames like
211125755750-pdc-prod-dac-data. (30 chars)
but this works fine
211125755750-pdc-prod-dac (25 characters)

Both should be acceptable as they are not longer than 63 octets.

I'll propose a patch shortly.
