I’ll have to look into it later. It seems to just be this link lol I can’t recreate the issue. Maybe you’re right and the issue is with Lemmy.world? Very strange
If it's any help/clue, I got the message when clicking it through Thunder (2 attempts), which opened Iceraven/FF and presented the error. Then I opened Iceraven/FF and did a typical search engine query, which worked.
Following up on this! I figured out why my link to Quiblr was acting funky. It was an issue on the hosting side with how the https certificate was set up... Basically it was set up for https://quiblr.com (no "www") and not "www.quiblr.com"
