Raspberry Pi Connect • Raspberry Pi Connect does not work without IPv6

TLDR: Somehow, my Raspberry Pi Connect only connected 10% of the time, but when I enabled IPv6 on my router, the connection is reliable and no more errors are reported.

My issue is similar to this post:

I just bought my first Raspberry Pi 5 a few weeks ago, and trying to connect to it via RPi Connect was one of the first things I tried. It worked very sporadically, and I followed the troubleshooting steps in the documentation (https://www.raspberrypi.com/documentati ... mon-issues):

I ran multiple times, and sometimes it would pass all 4 checks, or it would only pass 2, or just 1. always showed that I was logged in.

I finally enabled enhanced logging, and found that it sometimes reported errors such as the one in the aforementioned post:I then ran the curl command as mentioned in the post:And noticed that while the IPv4 address had no issues, the IPv6 address had errors.
I went back to the enhanced logs, and noticed that the errors were all IPv6.

I recalled turning off IPv6 on my router a few months ago for other reasons, and when I turned it back on, voila, Raspberry Pi Connect worked like a charm!

Just putting it out there, that this might be the reason for some issues.
