My domain is: gofb.info
My web server is (include version): short.io link shortner service
When we share short links from gofb.info on instagram and other social media platforms, we have a handful of users report that they get the message “this sites security certificate is not trusted” usually from the in-app (instagram / facebook) browser when users swipe up on the links.
Again, small number of users (we are working to get device information), but I am trying to gather information to create a support ticket with short.io on the topic.
SSL Labs shows a score of an A as well as trusted on Android, Apple, so I assume the chain is good.
Guess that the users are on older Android devices or using older versions of the native apps, but hard to trouble shoot directly.
Any advice is helpful.
