I deliberately set the constraint so that only HTTPS links would be considered valid wherever possible (since there's basically no reason for us not to link to the HTTPS versions of the sites instead of the HTTP versions). Partly also why it's only a suggestion constraint right now. The rest of the URL is fine and should be accepted.
It's better to have a bot change all HTTP to HTTPS first and then add the constraint. I get many references expanded now because of the constraint. It difficult for me to contribute now. And it's not my fault, I am not doing something wrong... So please or leave the constraint or with a bot make the needed changes.
The Google cache is not an archival service and should never be used as such (unless e.g. saved through archive.is). According to w:en:Wikipedia:List of web archives on Wikipedia, "links quickly expire".
Οκ. Thanks. I had a problem with a reference that wasn't archive anywhere else and I use Google cache. I have to find another solution.
Save the Google cache pages in archive.is or use the beta version of Save Page Now (login required) to save the original. The former should almost certainly work, and the latter may have a better chance of not messing up any formatting.
