Troubleshooting Twitter Preview

[LEckley]

Hi Guys,

Does anyone have a good method for troubleshooting why Twitter is refusing to provide an image preview?

Facebook has a developer tool which works well, but I am coming up short find a similar tool for Twitter.

Presently when sharing an image from one of my sites the preview card shows up on the Tweet, however the actual image never shows in the previewer.

Testing thus far...

• Confirmed working on Chevereto Demo
• Confirmed working on another Chevereto website not hosted by me.
• Cleared .htaccess for the external storage server, no change (The mirror is running Apache)
• Grabbed the working image from the demo and tried on my site, no cigar (Thought maybe it was a size issue, etc.)

Thoughts?

Thank you, I found it shortly after posting the above and in using it I am not finding an error.

So I am not entirely sure what is going wrong, still scratching my head.

Alright, issue resolved.

It came down to the IPs being listed in Twitter's documentation being incomplete/incorrect. Once I looked up their ASN and did a bit of digging I located their correct IP ranges and made the applicable changes resulting in everything now working correctly.

It happens all the time ¯\_(ツ)_/¯

It only took me a good 2 hours of troubleshooting to realize their docs were wrong. /facepalm

Thanks for the help!
