Connection Timing Out

[bobbyl140]

I just found this plugin, which seems to be the only one like this with 1.20 support. I uploaded an image to my web server, loaded it successfully in a browser, selected some item frames, then ran /if create test <url> selection. It took a few minutes to show any sign of activity, then spit out the following in the console:

Perhaps your webserver is blocking the request? Have you tried whether the same thing happens with other image hosting? (Don't try imgur)
