So, I was looking at post #2263546 and tried the source link https://yellow.ribbon.to/~pukarin/gallery/01mgxby/mnms01.htm
It didn't work and after bashing my head against the keyborad for a couple minutes I figured that if I replaced https with http the source link would work.
I then tried updating said source link with this change but e621 autocorrects the link back to https.
The link IS correct, and I am aware that https is more secure than http, but for this case https does not work. Is there anything that can be done about this?
