I tried to post a normal comment in c/linux4noobs@programming.dev It contained a hyperlink to YouTube and another one to Blufin Linux distro's website. When I tried to preview the comment, it didn't do anything, so I decided to post and it didn't work, either, but shown me this error. Is that some networking issue?

I expect that was a transient network issue that won't happen next time you comment.

It's happening again, this time I'm trying to post to https://piefed.social/c/degoogle@lemmy.ml
I lost the contents of my message because of that -- would it be possible to reload the page with the message intact when an error like this happens?

@rimu@piefed.social I know what's happening. I didn't notice it at first. When you use the hyperlink button to make a word in your post into a hyperlink, it automatically adds the "https://" part, but if your clipboard has the full HTTPS url for some resource, it becomes "https://https://" in PieFed and if you try to submit, it will return that error and your message is now gone. I think the easiest fix would be to check if the URL has the scheme and strip it.
