Hey, Some people reported that they have trouble labelling edits in wikilabels [1] (specially for Wikidata and that's why I'm cross-posting to wikidata-l too). That was due to the fact that wikilabels is behind a proxy on cloud VPS which confuses the application and sometimes it thinks the request is made over HTTP and changes the links/redirects to http instead of https and basically jumping over to SSL and not-SSL continuously causing OAuth redirect loops (because cookies can't jump around like requests). There were several options but the most secure and sane one was to enforce SSL and tell the application to consider everything as SSL request.

This would solve lots of bugs and issues in wikilabels. We apologize for any inconvenience caused by it. It was difficult to understand the underlying problem because it was happening for some people and not all and was hard to reproduce the bug.

Also, If you encounter any (new) issue, Please let me know immediately.
