We’re having a strange issue that seems to have started occurring only recently without any changes to SSL or DNS setup.
When some users copy a link to our domain and paste it without the prepending https://, (i.e. pasting domain.com/link into an Incognito address bar directly, they get a repeatable ERR_SSL_PROTOCOL_ERROR in Chrome.
However, when clicking the link directly from a page in another tab, it loads fine. Even if the clicked link does not include the “https://”.
Strangely, this can’t be reproduced at all for us on our side in any of the conditions (incognito, different devices, changed DNS gateway, with/without https:// prepended), but multiple users have provided videos of this occurring.
