Error code 7 while on wifi

hello. I have been having trouble connecting to IF because every time I’m on my home wifi I get an error code 7 alerts. I change to my phone’s hotspot and it works. I switch back to my wifi and it works fine. does anyone have this issue?

Maybe it’s connected to this:

how recent was that?

The topic is from 6 days ago, and since IPv6-only (as far as I know) is relatively new I think this is a new issue

ok. ive been having this issue for abt a month. ill check it out thanks!
