Tonight I was getting some SSL errors from Firefox:

Code: [Select]
Secure Connection Failed

The connection to fractalforums.org was interrupted while the page was loading.

I investigated with wget, seems that the issue is IPv4 (works) vs IPv6 (doesn't work):

in Firefox about:config toggling network.dns.disableIPv6 key allows me to browse the forums again, but this is a bit unsatisfactory (it disables IPv6 globally).

when I visit your Profile->Profile Info->Track User...->Activity I see ipv6 numbers so it was certainly working until very recently, will dig into it asap.

any input is appreciated :)

edit: wget -6 https://fractalforums.org -S = 2001:8d8:100f:f000::212|:443... failed: Network is unreachable.
not forum code ? maybe 1&1 ?

at the bottom of all pages you will see a little green icon that says "ipv6 ready" if that goes red then ipv6 is not available,
in order to load that badge the referrer, fractalforums.org, must be a valid ipv6 site.

let me know if you see green or red.

I see green (this time connected from my laptop via WIFI to my router, previously wired connection, with a different browser - firefox 60 instead of 52)

I guess it was just a temporary issue, seems fixed now (no issues browsing, I see an IPv6 address next to some recent posts of mine, so I guess all is fine).
