Link Previews not working in all cases

[jclabaugh]

I have found multiple URLs that show a link preview in Slack but do not in Rocket.Chat.

Examples:

The 2nd and 3rd work for me. The first still doesn't

on Slack, the first link previews like this

An interesting note.. When I curl the link, curl thinks that link has invalid ssl. This may be the reason..

[jclabaugh]

could add the command line switch (-k or --insecure) when using curl so that it doesn't disregard wildcard cert's for subdomains or self-signed cert's

Allow connections to SSL sites without certs

Right that's what I did as soon as it failed. Let me verify this is actually what's happening on rocket.chat.

This might be what's happening with your other issue as well.
